Description

  The present invention relates to a clock, a correction method thereof, an information processing apparatus and method, and a program, and in particular, a clock and a correction method thereof, in which time correction of a clock moved to a different time zone can be easily performed, The present invention relates to an information processing apparatus and method, and a program.

  In recent years, in addition to mechanical watches, many electronic watches (see, for example, Patent Document 1) have appeared. Conventionally, when performing time correction of such an electronic timepiece, generally, the following first conventional correction method or second conventional correction method has been employed.

  The first conventional correction method is a method in which the user himself / herself operates an electronic timepiece to perform time correction. The second conventional correction method is a method of having an antenna inside an electronic timepiece, receiving a standard radio wave, and automatically correcting the time.

JP 2003-29868 A

  However, in the first conventional correction method, since the user's setting operation is indispensable, the correction content / timing must be taken into consideration by the user. Therefore, every time the user moves to an area with a different time zone together with the electronic timepiece, a setting operation for time correction is necessary, and such a setting operation often feels complicated.

  On the other hand, in the second conventional correction method, such a setting operation is unnecessary, but in order to realize time correction, it is necessary to incorporate an antenna module in the electronic timepiece. For this reason, when the electronic timepiece moves to an area with a different time zone, the second conventional correction method itself cannot be used at all. For example, if an electronic timepiece for Japanese standard radio waves is used in other countries, it will not be possible to receive standard radio waves in other countries due to differences in frequency and time code, and as a result, the second conventional correction method itself cannot be used at all. .

  From the above, in the event that the user moves to an area with a different time zone together with the electronic watch, in order to correct the time of the electronic watch, the setting operation by the first conventional correction method, Conventionally, there is a problem that a setting operation that would be complicated for the user is required.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a diagram showing a configuration example of the appearance of a wristwatch type electronic timepiece to which the present invention is applied.

  In the example of FIG. 1, when the electronic timepiece 1 is put on the user's (human) arm, the surface viewed by the user (the surface shown in FIG. 1 and hereinafter referred to as the surface) is a low-temperature polysilicon TFT ( An image display unit 2 composed of a thin film transistor (LCD) type liquid crystal display (LCD) or the like is provided. On the surface of the electronic timepiece 1, tact switches 4-1 to 4-5 are provided for the user to input various information (commands, etc.). Hereinafter, when it is not necessary to distinguish each of the tact switches 4-1 to 4-5 from each other, they are collectively referred to as a tact switch 4.

  Further, a connector portion 3 is provided on the back surface (surface facing the front surface) or side surface (surface substantially perpendicular to the front surface) of the electronic timepiece 1. The connector unit 3 is connected to an external device such as the device 11 shown in FIG. 2 and the network device 41 shown in FIG. Then, the electronic timepiece 1 can exchange various information and power with an external device via the connector unit 3. In this case, the connection form between the electronic timepiece 1 and the external device via the connector unit 3 is not particularly limited, but in the present embodiment, connection according to the USB (Universal Serial Bus) standard (hereinafter referred to as USB connection) is used. Suppose it is done. This is because the electronic timepiece 1 can be charged from an external device, and various information can be exchanged between the electronic timepiece 1 and the external device. Therefore, in the present embodiment, the connector unit 3 is configured as a USB-compliant connector.

  FIG. 2 is a functional block diagram showing an example of a functional configuration inside the electronic timepiece 1 having the external configuration of FIG.

  In the example of FIG. 2, the electronic timepiece 1 is provided with a power supply unit 21 to a display data generation unit 25 in addition to the image display unit 2 and the connector unit 3 described above.

  The power supply unit 21 provides power to the entire system (here, the entire electronic timepiece 1). In the present embodiment, the charging operation for the power supply unit 21 is performed by electric power provided from an external device (the device 11 in the example of FIG. 2) connected by the connector unit 3 described later.

  The timekeeping unit 22 performs a timekeeping operation using, for example, GMT (Greenwich Mean Time), and causes the storage unit 23 to store time information indicating a result of the timekeeping, that is, “time regarded as the current GMT”. The reason that “the time considered to be the current GMT” is described is that the time measured by the time measuring unit 22 does not necessarily match the actual GMT (may be deviated from GMT). However, hereinafter, for the sake of simplicity, “time regarded as current GMT” is simply referred to as reference time, and time information indicating “time regarded as current GMT” is simply referred to as reference time information.

  The reference time information can be updated also by the time correction unit 24, as will be described later. That is, the reference time may be updated by the time correction unit 24. In such a case, the timekeeping unit 22 resets the previous timekeeping operation and restarts the timekeeping operation based on the corrected reference time.

  As described above, in the present embodiment, the storage unit 23 stores the reference time information. Further, in the present embodiment, the storage unit 23 also stores a table as shown in FIG.

  In the table of FIG. 3, one predetermined line corresponds to one predetermined time zone, and “TZ-ID”, “time zone name”, “time difference information (time)”, and “Daylight saving time” is described.

  “TZ-ID” is an identifier for specifying the time zone corresponding to the line. The “time zone name” is the name of the time zone corresponding to the line. “Time difference information (time)” is information indicating the time difference from GMT in the time zone corresponding to the row in time. “Daylight saving time presence / absence” is information indicating whether or not the time zone corresponding to the row adopts daylight saving time, “○ (circle)” indicates that daylight saving time is adopted, and “× (X) indicates that daylight saving time is not adopted.

  Specifically, for example, the time zone corresponding to the fourth line from the top is a time zone with “3” added as “TZ-ID”, and a time zone named “EEE”. Recognize. And the time difference with GMT in such a time zone is +2 hours, and it turns out that the daylight saving time is adopted.

  As described above, the table of FIG. 3 describes various information related to each time zone. Therefore, hereinafter, the table of FIG. 3 is referred to as a time zone table.

  Returning to FIG. 2, in the present embodiment, the storage unit 23 further stores information (hereinafter referred to as TZ-ID) for storing the TZ-ID of the time zone of the place where the electronic timepiece 1 currently exists (the place considered as such). ID information) is also stored.

  The time correction unit 24 is based on the above-described stored contents of the storage unit 23, that is, based on the reference time information, the time zone table (FIG. 3), and the TZ-ID information. The time (that is, the time indicated by the reference time information at that time) is corrected, and the corrected time information indicating the corrected time is provided to the display data generation unit 25. Here, the corrected time means the local time when the time zone specified by the TZ-ID information is local when the TZ-ID information is used.

  Further, as will be described later, there is time information indicating “the time to be regarded as the current GMT (here, it is also regarded as the time to be regarded because it may not be exactly coincident with GMT)” managed by the device 11. In some cases, the signal is transmitted from the device 11 to the connector unit 3.

  In such a case, the time correction unit 24 obtains the time information from the device 11 via the connector unit 3, the time indicated by the time information (hereinafter referred to as the acquisition time), and the storage unit 23 at that time. Compared to the reference time indicated by the stored reference time information (hereinafter referred to as the storage time), if it is different, the acquisition time is regarded as the correct current GMT, and the content of the reference time information is determined from the storage time. Update to acquisition time. That is, the reference time is updated to the acquisition time.

  Then, as described above, the time measuring unit 22 resets the previous time measuring operation and restarts the time measuring operation based on the acquisition time.

  Further details of the processing of the time correction unit 24 will be described later with reference to various flowcharts (for example, FIG. 4 and FIG. 5).

  The display data generation unit 25 presents an image for presenting the time specified by the corrected time information provided from the time correction unit 24, that is, the time corrected by the time correction unit 24 (local time, etc.). An image for this purpose is generated in the form of image data, and an image corresponding to the image data is controlled to be displayed on the image display unit 2.

  In this way, the image display unit 2 corrects the time corrected with respect to GMT, more precisely, the time corrected with respect to the reference time indicated by the reference time information (that is, the time regarded as GMT) ( Local time etc.) is displayed. Therefore, hereinafter, the corrected time (local time or the like) is referred to as a display time. The reason why the display time includes the local time and the like is because the time in the user's living area may be included in addition to the local time, as will be described later.

  The device 11 is composed of, for example, a personal computer, and manages a connector unit 31 that is connected to an external device (electronic watch 1 in the example of FIG. 2) via USB and exchanges various information, and “time regarded as the current GMT”. It is comprised so that the time management part 32 to perform may be included.

  Accordingly, the time management unit 32 can generate time information indicating “time to be regarded as the current GMT” and provide the time information to the electronic timepiece 1 via the connector unit 31.

  The time management unit 32 also manages the TZ-ID of the time zone of the place where the device 11 currently exists (the place considered as such), and the TZ-ID is also transmitted to the electronic timepiece 1 via the connector unit 31. Can be provided.

  Next, an example of processing of the electronic timepiece 1 having the configuration of FIG. 2 will be described with reference to the flowchart of FIG.

  In step S <b> 1, the electronic timepiece 1 determines whether or not the device 11 is connected via USB (connector unit 3).

  If it is determined in step S1 that the device 11 is not connected by USB, the process returns to step S1, and it is determined again whether the device 11 is connected by USB. That is, until the electronic timepiece 1 and the device 11 are connected via the connector portion 3 and the connector portion 31 (until the USB connection is established), the determination process in step S1 is repeatedly performed, and the processing of the electronic timepiece 1 is performed. It will be in a standby state.

  Thereafter, as shown in FIG. 2, when the electronic timepiece 1 and the device 11 are connected via the connector unit 3 and the connector unit 31, it is determined YES in the process of step S <b> 1, and the process is as follows. Proceed to step S2.

  In step S <b> 2, the power supply unit 21 supplies power from the connection destination device 11.

  In step S <b> 3, the time correction unit 24 obtains the time information of the connection destination device 11 via the connector unit 3.

  In step S <b> 4, the time correction unit 24 obtains the TZ-ID of the connection destination device 11 via the connector unit 3.

  In step S5, the time correction unit 24 has a storage time (a reference time indicated by the reference time information at that time in the storage unit 23) and an acquisition time (a time indicated by the time information acquired in the process of step S3). It is determined whether or not there is a mismatch.

  If it is determined in step S5 that the storage time and the acquisition time do not coincide with each other, the time correction unit 24 replaces the reference time information (reference time indicated by it) in the storage unit 23 with the acquisition time in step S6. Then, as described above, the time measuring unit 22 resets the previous time measuring operation and restarts the time measuring operation based on the acquisition time. Thereafter, the process proceeds to step S7.

  On the other hand, when it is determined in step S5 that the storage time and the acquisition time are not inconsistent (matched), the process in step S6 is not executed, that is, the reference time in the storage unit 23. The information is not updated, and as a result, the processing proceeds to step S7 while the timing operation of the timing unit 22 continues without being reset.

  In step S7, the time correction unit 24 stores the saved TZ-ID (the TZ-ID stored in the current TZ-ID information in the storage unit 23) and the obtained TZ-ID (obtained in the process of step S4). It is determined whether or not the TZ-ID of the device 11 is inconsistent.

  If it is determined in step S7 that the saved TZ-ID and the obtained TZ-ID do not match, the time correction unit 24 replaces the TZ-ID information in the storage unit 23 with the obtained TZ-ID in step S8 ( Generate TZ-ID information that stores the obtained TZ-ID). Thereby, a process progresses to step S9.

  On the other hand, when it is determined in step S7 that the saved TZ-ID and the obtained TZ-ID are not inconsistent (matched), the process in step S8 is not executed, that is, the storage unit 23. The TZ-ID information is not updated (the stored TZ-ID is stored in the TZ-ID information), and the process proceeds to step S9.

  In step S9, for example, a time display process shown in FIG. 5 is executed. That is, the flowchart of FIG. 5 shows a detailed example of the time display process.

  In step S <b> 21, the time correction unit 24 determines the correction amount from the TZ-ID information and the daylight saving time information in the storage unit 23.

  In the present embodiment, the daylight saving time information means “the presence / absence of daylight saving time” in the time table of FIG. The correction amount is a correction time with respect to GMT, more precisely, a correction time with respect to the reference time indicated by the reference time information in the storage unit 23 (that is, the time regarded as the current GMT).

  Therefore, for example, the following series of processes is executed here as the process of step S24. That is, the time correction unit 24 recognizes the TZ-ID stored in the TZ-ID information in the storage unit 23. The time correction unit 24 describes the line corresponding to the recognized TZ-ID in the time zone table in the storage unit 23, that is, the recognized TZ-ID is described in the item “TZ-ID”. Let the line be a noteworthy line. The time correction unit 24 acquires “time difference information (time)” and “presence / absence of daylight saving time” of the row of interest. Then, the time correction unit 24 determines the correction amount based on the acquired “time difference information (time)” and “presence / absence of daylight saving time”.

  Specifically, for example, when the TZ-ID stored in the TZ-ID information is “3”, in the example of FIG. 3, the fourth row from the top, that is, the time zone named “EEE” The line about is the attention line. In this case, “2” that is “time difference information (time)” of the attention row is acquired, and “◯” that is “existence of daylight saving time” is acquired. Accordingly, if the current time is the time when summer time is being implemented (summer time, etc.), +1 hour (= 2 hours of time difference-one hour of summer time) is determined as the correction amount. On the other hand, if the current time is a time when summer time is not implemented (time such as winter), +2 hours (= only 2 hours of time difference) is determined as the correction amount.

  In step S22, the time correction unit 24 obtains the display time from the reference time information in the storage unit 23 and the correction amount determined in the process of step S21.

  Specifically, for example, in the above-described example, if the current time is the time when daylight saving time is in effect, +1 hour is determined as the correction amount, so the reference time (GMT) indicated by the reference time information in the storage unit 23 The time that is delayed by one hour with respect to the time considered as the display time is obtained as the display time.

  In step S23, the time correction unit 24 sends the display time (more accurately, corrected time information indicating the time) to the display data generation unit 25.

  In step S24, the display data generation unit 25 creates a display image reflecting the display time in the form of image data. In step S25, the display data generation unit 25 controls the image display unit 2 to display the display image.

  Thereby, the time display process is ended. That is, step S9 in FIG. 4 ends, and the entire processing of the electronic timepiece 1 ends.

  As described above, the electronic timepiece 1 of the example of FIG. 2 can execute the processing according to the flowchart of FIG. 4, for example, so that even when it is moved to a different time zone, it is connected to the device 11 existing at that location. Thus, the time zone can be automatically changed without forcing the user to perform complicated setting operations associated with the change of the time zone, and the local time at the place can be displayed on the image display unit 2 as the display time. . That is, for the user, even when the electronic timepiece 1 is moved to a location in a different time zone, it is not particularly necessary to perform a complicated setting operation associated with the change of the time zone. By simply performing a simple operation such as connecting the electronic timepiece 1, it is possible to easily recognize the local time of the place.

  By the way, in the example of FIG. 2, as the reference time used for time correction of the electronic timepiece 1, the time managed in the connection destination device 11 (the time indicated by the time information obtained in the process of step S <b> 3 in FIG. 4). However, such a time is not necessarily an accurate time (matching GMT) as described above as “a time regarded as the current GMT”.

  Therefore, when further accuracy of the reference time is required, that is, when it is desired to use a time closer to GMT as the reference time, for example, instead of the device 11 in the example of FIG. What is necessary is just to connect the network apparatus 41 shown by FIG.

  That is, as shown in FIG. 7, the network device 41 is provided with a connector unit 31 and a time management unit 32 similar to those of the device 11 in the example of FIG. 2, and further connected to a network 42 such as the Internet. A possible network connection 51 is also provided.

  As a result, the time management unit 32 of the network device 41 receives the time indicating the network standard time from the NTP server 43 (FIG. 6) that manages the network standard time in the network 42 (a time closer to the current GMT). Information (hereinafter, referred to as network standard time information to be distinguished from other time information) can be obtained via the network connection unit 51. Therefore, the time management unit 32 can provide the network standard time information to the electronic timepiece 1 via the connector unit 31.

  In other words, the electronic timepiece 1 can use the network standard time, which is a time closer to the current GMT (a time with little deviation from GMT), as the reference time. However, in this case, it is assumed that the electronic timepiece 1 has an SNTP (Simple Network Time Protocol) client function.

  Hereinafter, an example of processing of the electronic timepiece 1 when connected to the network device 41 of the example of FIG. 7 will be described with reference to the flowchart of FIG.

  In step S41, the electronic timepiece 1 determines whether or not the network device 41 is connected via USB (connector unit 3).

  If it is determined in step S41 that the network device 41 is not connected by USB, the process returns to step S41, and it is determined again whether the network device 41 is connected by USB. That is, until the electronic timepiece 1 and the network device 41 are connected via the connector unit 3 and the connector unit 31 (until the USB connection is established), the determination processing in step S41 is repeatedly executed, and the processing of the electronic timepiece 1 is performed. Is in a standby state.

  Thereafter, as shown in FIG. 7, when the electronic timepiece 1 and the network device 41 are connected via the connector unit 3 and the connector unit 31, it is determined as YES in the process of step S41, and the process Advances to step S42.

  In step S <b> 42, the power supply unit 21 supplies power from the network device 41.

  In step S <b> 43, the electronic timepiece 1 determines whether the network device 41 is connected to the network 42.

  If it is determined in step S43 that the network device 41 is not connected to the network 42, the electronic timepiece 1 waits for a certain time in step S44. That is, when a certain time has elapsed, the process proceeds to step S45.

  In step S45, the electronic timepiece 1 determines whether or not the network device 42 is still connected to the USB.

  If it is determined in step S45 that the network device 42 is not connected to the USB, the entire process ends.

  In contrast, if it is determined in step S45 that the network device 42 is still connected to the USB, the process returns to step S43, and the subsequent processes are repeated. That is, until the network device 41 is connected to the network 42 (however, it is necessary that the electronic timepiece 1 and the network device 42 are connected by USB), the loop processing of steps S43 to S45 is repeatedly executed, The processing of the timepiece 1 is in a standby state.

  Thereafter, when the network device 41 is connected to the network 42 (or immediately after being connected to the network 42 in advance), it is determined YES in the process of step S43, and the process proceeds to step S46.

  In step S <b> 46, the time correction unit 24 obtains network standard time information and TZ-ID from the network device 41 via the connector unit 3.

  Specifically, for example, the following series of processes is executed as the process of step S46.

  That is, the time correction unit 24 makes an inquiry about the network standard time to the NTP server 43 (FIG. 6) via the USB (connector unit 3) and the network device 41 using the SNTP client function described above.

  In response to this inquiry, the network device 41 obtains network standard time information from the NTP server 43. At this time, the network device 41 obtains Time Zone information from DHCP (Dynamic Host configuration Protocol) setting information as communication path information. The network device 41 generates a TZ-ID from the Time Zone information. Then, the network device 41 transmits the network standard time information and the TZ-ID to the electronic timepiece 1. A series of detailed examples of the network device 41 will be described later with reference to the flowchart of FIG.

  Then, the time correction unit 24 acquires the network standard time information and the TZ-ID from the network device 41 via the connector unit 3.

  When such a series of processes is executed as the process of step S46, the process proceeds to step S47.

  Note that the processes in steps S47 to S51 are basically the same as the processes in steps S5 to S9 of FIG. 4 described above (however, the acquisition time is the network standard time in the example of FIG. 8). However, description of these processes is omitted here.

  Next, processing on the network device 41 side with respect to the processing of the electronic timepiece 1 of FIG. 8 will be described with reference to the flowchart of FIG. Such processing can be realized by an application that obtains time information using a so-called time server service (daemon), for example, GetSystemTime (), GetLocalTime (), etc. of Windows (registered trademark) API (trademark).

  The process of FIG. 9 is executed when the power state of the network device 41 is turned on. In other words, the processing in FIG. 9 ends at that point when the power state of the network device 41 is turned off.

  In step S71, the time management unit 32 (FIG. 7) of the network device 41 sleeps for a predetermined time. Note that the fixed time, that is, the sleep interval can be changed at any time except during the sleep in the process of step S71.

  After the predetermined time Sleep, the process proceeds to Step S72. In step S <b> 72, the time management unit 32 determines whether an inquiry for obtaining the network standard time has been received from the electronic timepiece 1.

  If it is determined in step S72 that an inquiry has not been received from the electronic timepiece 1, the process returns to step S71, and the subsequent processes are repeated. In other words, the loop processing of steps S71 and S72 is repeatedly executed until an inquiry for obtaining the network standard time is received from the electronic timepiece 1, and the processing (daemon) of the network device 41 is in a standby state.

  For example, in the present embodiment, as described above, the electronic timepiece 1 determines YES in the process of step S43 in FIG. 8 and starts the process of step S46, and inquires about the network standard time. At this time, it is determined as YES in Step S72, and the process proceeds to Step S73.

  In step S <b> 73, the time management unit 32 obtains DHCP option code = 88 information as time zone information from the network 42 via the network connection unit 51. In step S74, the time management unit 32 generates a TZ-ID from the time zone information.

  In step S <b> 75, the time management unit 32 obtains information about DHCP option Code = 42 from the network 42 via the network connection unit 51. Since this information is information of the NTP server 43 (FIG. 6), in step S76, the time management unit 32 obtains the network standard time information (so-called UTC information) from the NTP server 43, the network connection unit 51, and the network 42. Get through.

  In step S 77, the time management unit 32 transmits the TZ-ID and network standard time information to the electronic timepiece 1 via the connector unit 31. Thereafter, the process returns to step S71, and the subsequent processes are repeated.

  At this time, for example, on the electronic timepiece 1 side of the present embodiment, as described above, the time correction unit 24 uses the network standard time information and the TZ-ID as the connector unit as part of the processing in step S46 of FIG. 3 and then the process proceeds to step S47.

  By the way, in the above-described example, since only one TZ-ID information is stored in the storage unit 23, when the electronic timepiece 1 is moved to a location in a time zone other than the user's living area, the destination Only the time according to the time zone is displayed on the image display unit 2 as the display time. Therefore, since it becomes difficult to know the time of the living area with this, it is imagined that the user will give a desire to display the time of the living area at the same time or to display it by switching. Not difficult.

  In this case, in order to meet such a demand, the time correction unit 24 individually manages the living area time as the master time and the destination time as the sub time, and the display data generation unit 25 performs the predetermined tact switch 4. In accordance with the operation of (FIG. 1), an image including only the master time is displayed on the image display unit 2, an image including only the sub time is displayed on the image display unit 2, or the master time and the sub time May be displayed on the image display unit 2.

  Specifically, for example, the TZ-ID information storing the TZ-ID of the time zone of the user's living area is stored in the storage unit 23 as TZ-ID information for master time, and for other areas (destination area) TZ-ID information may be stored in the storage unit 23 as sub-time TZ-ID information.

  In this case, the master time TZ-ID information is generated at the time of manufacture of the electronic timepiece 1 or at various settings after purchase, and is stored in the storage unit 23. Thereafter, updating is prohibited (the update is prohibited). In order to allow it, a special operation may be required). Further, it is assumed that the sub TZ-ID information is also generated at this time (however, the TZ-ID stored as the initial setting value at this time may be arbitrary) and stored in the storage unit 23. It is assumed that the sub-TZ-ID information is allowed to be updated by the time correction unit 24.

  Then, in steps S7 and S8 in FIG. 4 and steps S49 and S50 in FIG. 8 described above, each process may be executed for the sub TZ-ID information. In the time display process of FIG. 5, the processes of steps S21 to S23 may be performed independently for each of the master time and the sub time. That is, the master display time to be displayed as the master time and the sub display time to be displayed as the sub time may be obtained and sent to the display data generation unit. In step S24, an image corresponding to the operation of a predetermined tact switch 4 (FIG. 1), that is, a display image including only the master display time, a display image including only the sub display time, or a master display time A display image including the sub display time may be created at the same time, and the created display image may be displayed on the image display unit 2 in the next step S25.

  By the way, in the above-described example, when the user moves to an area having a different time zone together with the electronic timepiece (the electronic timepiece 1 in FIG. 1 or the like in the above-described example), the electronic timepiece is corrected in order to correct the time of the electronic timepiece. It is necessary to perform an operation for connecting the watch to an external device (in the above-described example, the device 11 in FIG. 2, the network device 41 in FIG. 7, etc.).

  Therefore, in the above-described example, when there is no external device in the vicinity of the user's moving location, the time correction of the electronic timepiece cannot be performed. In addition, it is not difficult to imagine that the user often feels that the operation of connecting the electronic timepiece to the external device is troublesome in many cases, assuming that the user frequently moves with the electronic timepiece.

  Therefore, in such a case, it is convenient that the electronic timepiece automatically performs a process of correcting the display time to the local time according to the movement of the electronic timepiece (performed by the user's own judgment without any user operation). is there. One embodiment of an electronic timepiece capable of executing such automatic processing is shown in FIGS.

  In the example of FIG. 10, the electronic timepiece 61 performs wireless communication with the router 62 according to the IPv6 (Internet Protocol Version 6) standard, so that other devices on the network 42 via the router 62 (example of FIG. 10). Now, various information can be exchanged between the NTP server 43 and a time zone search server 64) to be described later.

  Specifically, for example, the electronic timepiece 61 can be configured as shown in FIG. That is, in the example of FIG. 11, the electronic timepiece 61 includes a power supply unit 71 in addition to the image display unit 2 and the timekeeping unit 22 through the display data generation unit 25 similar to the electronic timepiece 1 (see FIG. 2 and the like) described above. A communication unit 72 is provided.

  The power supply unit 71 provides power to the entire system (here, the entire electronic timepiece 61). Although not shown in FIG. 11, the electronic timepiece 61 can also be equipped with a connector portion 3 that can be connected to an external device (for example, the device 11 in FIG. 2 or the network device 41 in FIG. 7). Yes, that is, it is possible to mount a function capable of USB connection with an external device. In this case, the power supply unit 71 can be charged using the power provided from the external device connected to the connector unit 3. become.

  The communication unit 72 executes various processes for performing wireless communication with the router 62 in accordance with the IPv6 standard.

  Here, an outline of IPv6 will be described. IPv6 is realized by the protocol shown in FIG. Such a protocol is an ID (Internet protocol) that is always distributed to a network device (here, an electronic timepiece 61 that is a network device for the network 42 in FIG. 10). Such an ID is hereinafter referred to as an IPv6 address.

  As shown in FIG. 12, the IPv6 address is 128 bits long. Of these, the upper-order 64-bit data 81 is generally used as an identifier (prefix) of a network (here, the network 42 in FIG. 10). The lower 64-bit data 82 is used as a host identifier (interface ID) in the network. Therefore, in the following, in the IPv6 address, the upper 64-bit data 81 is referred to as a network ID 81, and the lower 64-bit data 82 is referred to as an interface ID 82.

  The network ID 81 is composed of information of 3-bit FP, 13-bit TLA ID, 8-bit reservation, 24-bit NLA ID, and 16-bit SLA ID. The details of each information of FP, TLA ID, reservation, NLA ID, and SLA ID are as shown in FIG.

  The network ID 81 is uniquely determined by the provider or the like. Here, for example, it is assumed that a unique network ID 81 is determined for the router 62 of FIG.

The network ID 81 is, for example, APNI (http://www.apnic.net/) in the Asia Pacific region, ARIN (http://www.arin.net/) in the North America region, and RIPE NCC ( http://www.ripe.net/), LACNIC (http://lacnic.net/en/) in Latin America and AfriNIC (http://www.afrinic.net/
). Hereinafter, an organization that manages the network ID 81, such as APNIC, is referred to as a network ID management organization.

  In IPv6, a so-called “plug and play” function can be realized. This function is generally referred to as “stateless address automatic setting” and refers to a function in which the host itself automatically sets its own IPv6 address to the client.

  Therefore, by using this “plug and play”, the router 62 (FIG. 10) functioning as a host can connect the electronic timepiece 61 functioning as a client to the network 42 without a DHCP server. As a result, manual setting by the user becomes unnecessary. That is, in the example of FIG. 10, when the electronic timepiece 61 moves to a range where wireless communication with the router 62 is possible, wireless communication with the router 62 is established / started. At this time, the router 62 establishes (transmits) an IPv6 address including the network ID 81 in the electronic timepiece 61 as communication path information, thereby connecting to the network 42.

  In this case, if the time zone search server 64 in FIG. 10 can acquire the network ID 81 of the IPv6 addresses set in the electronic timepiece 61, the ID-provider information provided by the network ID management organization, the usage area information by the provider, It is possible to specify in which time zone the electronic timepiece 61 is located.

  However, since IPv6 is a technology that is being introduced at the time of filing this application, ID-provider information may not be available. Therefore, in the present embodiment, the time zone search server 64 holds, for example, a table shown in FIG. 14 instead of the ID-provider information provided by the network ID management organization and the use area information provided by the provider. And

  In the table of FIG. 14, one predetermined line corresponds to one predetermined IPv6 address (network ID 81). In addition to the “IP address (upper 64 bits)” indicating the network ID 81 of the IPv6 address, the network “Time zone name”, “TZ-ID”, “Time difference information (time)”, “Presence / absence of daylight saving time” are described as information about the time zone specified by ID 81, and “Nearest NTP server information” is is described.

  Each of the “time zone name”, “TZ-ID”, “time difference information (time)”, and “presence / absence of daylight saving time” is the same information as the corresponding name information in the time zone table of FIG. Therefore, the description thereof is omitted.

  “Nearest NTP server information” is information (such as a URL) indicating the location of the NTP server closest to the time zone area specified by the network ID 81.

  As described above, the table of FIG. 14 describes various information related to the time zone specified from each IPv6 address (network ID 81). That is, by referring to the table of FIG. 14, the corresponding time zone can be specified from a predetermined IPv6 address (network ID 81). Therefore, hereinafter, the table of FIG. 14 is referred to as a time zone specifying table.

  In this case, the time zone search server 64 in FIG. 10 acquires the IPv6 address set in the electronic timepiece 61 via the router 62 and the network 42, thereby referring to the time zone specifying table in FIG. A zone can be specified. In addition, the time zone search server 64 can transmit the TZ-ID of the specified time zone to the electronic timepiece 61 via the network 42 and the router 62. Details of the processing of the time zone search server 64 will be described later with reference to the flowchart of FIG.

  In other words, the electronic timepiece 61 establishes wireless communication with the router 62, and after setting the IPv6 address accordingly, transmits the IPv6 address to the time zone search server 64, thereby obtaining the TZ-ID. Available. That is, the electronic timepiece 61 can specify the time zone of the movement location (obtain TZ-ID) according to its movement. Therefore, after that, the electronic timepiece 61 communicates with the NTP server 43 to obtain the network standard time information in the same manner as the electronic timepiece 1 described above, thereby correcting the display time to the local time of the moving place. Can be displayed on the image display unit 2.

  In this case, when viewed from the user, when there is no external device in the vicinity of the user's moving location, or when the user frequently moves with the electronic watch, the user has various troubles including connection operation to the external device. Even without a simple operation, the local time of the moving place is displayed as the display time on the image display unit 2 of the electronic timepiece 61, which is very convenient.

  A detailed example of the processing of the electronic timepiece 61 will be described below with reference to the flowchart of FIG.

  When the electronic timepiece 61 moves to a range where wireless communication with the router 62 is possible, the electronic timepiece 61 starts the processing of FIG.

  In step S <b> 101, the communication unit 72 (FIG. 11) of the wrist watch 61 establishes / starts wireless communication with the router 62. At this time, as described above, an IPv6 address (FIG. 12) is provided (set) from the router 62 to the communication unit 72 as communication path information.

  In step S102, the communication unit 72 makes an area request by transmitting this communication path information (IPv6 address) to the time zone search server 64 via the router 62 and the network 42 (FIG. 10).

  At this time, the time zone search server 64 performs processing according to the flowchart of FIG. 16, for example.

  That is, in step S121 in FIG. 16, the time zone search server 64 determines whether or not there is an area request from the electronic timepiece 61, that is, whether or not a client ID has been acquired. Note that the client ID refers to, for example, the network ID 81 in the IPv address transmitted from the electronic timepiece 61 in the present embodiment.

  Therefore, unless the communication route information (IPv6 address) is transmitted from the electronic timepiece 61 by the processing in step S102 described above, it is determined in step S121 that there is no area request from the electronic timepiece 61, and the processing returns to step S121. Then, it is determined again whether or not there is an area request from the electronic timepiece 61. That is, until the communication path information (IPv6 address) is transmitted from the electronic timepiece 61 by the process of step S102, the determination process of step S121 is repeated, so that the processing state of the time zone search server 64 is set to the standby state. Become.

  Then, when the communication path information (IPv6 address) is transmitted from the electronic timepiece 61 by the processing of step S102 described above, it is determined in step S121 that there is an area request from the electronic timepiece 61, and the processing proceeds to step S122. .

  In step S122, the time zone search server 64 determines whether there is a client ID in the time zone specifying table of FIG. 14, for example, that is, the item “IP address (upper 64 bits)” includes the client ID. Determine if a row exists.

  In step S122, when it is determined that the client ID is in the table, the time zone search server 64 in step S123, the area information corresponding to the client ID ("TZ- described in the corresponding row of the table" ID "and" Nearest NTP server information "). That is, the area information is transmitted from the time zone search server 64 to the electronic timepiece 61 via the network 42 (FIG. 10) and the router 62. Thereby, the process of the time zone search server 64 is complete | finished.

  On the other hand, if it is determined in step S122 that there is no client ID in the table, the time zone search server 64 determines in step S124 that there is an area error (information indicating that there is no area information corresponding to the client ID). )return it. That is, such an area error is transmitted from the time zone search server 64 to the electronic timepiece 61 via the network 42 and the router 62.

  In this way, when area information or area error is transmitted from the time zone search server 64, the time correction unit 24 (FIG. 11) of the electronic timepiece 61 executes the determination process of step S103 of FIG. That is, in step S103, the time correction unit 24 determines whether an area error has occurred.

  When an area error has been transmitted (when the process of step S124 in FIG. 16 is executed), it is determined YES in the process of step S103, and the process proceeds to step S104. That is, in step S104, when the time correction unit 24 acquires the area error via the communication unit 72, the time correction unit 24 stores the saved TZ-ID (the TZ-ID stored in the current TZ-ID information in the storage unit 23). ) Is regarded as an obtained TZ-ID (TZ-ID to be obtained as a response from the time zone search server 64 in response to the area request of the processing in step S102).

  On the other hand, when area information (“TZ-ID”, “nearest NTP server information”, etc.) is transmitted (when the process of step S123 in FIG. 16 is executed), the process of step S103 is performed. If it is determined as NO, the process proceeds to step S105. In step S <b> 105, the time correction unit 24 obtains the area information via the communication unit 72. That is, in this case, the “TZ-ID” included in the area information becomes the obtained TZ-ID (see steps S109 and S110 described later). Further, the network standard time information is obtained from the NTP server (NTP server 43 in the example of FIG. 10) specified by “nearest NTP server information” included in the area information (see step S106 described later). .

  In this way, when the process of step S104 or S105 is executed, the process proceeds to step S106.

  In step S <b> 106, the time correction unit 24 obtains network standard time information from the NTP server 43 via the communication unit 72, the router 62, and the network 42. In this manner, when the process of step S106 is executed, the process proceeds to step S107.

  Note that the processes of steps S107 to S111 are basically the same as the processes of steps S47 to S51 of FIG. 8 described above, and therefore description of these processes is omitted here.

  As the processing in step S102, in the example of FIG. 15, processing for transmitting the entire IPv6 address to the time zone search server 64 is adopted. However, as described above, the time zone search server 64 side specifies the time zone using only the network ID 81 (FIG. 12). Therefore, a process of transmitting only the network ID 81 to the time zone search server 64 may be employed as the process of step S102.

  Further, if the electronic timepiece 61 has a function of connecting to an external device via USB or the like (provided with the connector unit 3 of FIG. 2 or the like), in addition to the processing according to the flowchart of FIG. For example, the display time can be corrected by executing the processing according to the flowcharts of FIGS. 4 and 8 described above.

  Furthermore, in the example of FIG. 10, the time zone search server 64 is provided. However, the time zone search server 64 is omitted, and the function of the time zone search server 64 is replaced with the NTP server 43 or the router 62 instead. You may make it mount. That is, the NTP server 43 or the router 62 may hold the time zone specifying table shown in FIG. 14, for example, and execute the process shown in FIG.

  As described above, the timepiece to which the present invention is applied (for example, the electronic timepiece 1 in FIG. 1 and the electronic timepiece 61 in FIG. 10) is variously obtained from an external device connected via USB or an external device on a network. Information (communication route information, connection information, etc.) is used to automatically determine the time zone of its own location and obtain the standard time (network standard time, etc.), so that the display time It is possible to execute a time correction process such as correcting to the local time.

  Furthermore, the timepiece to which the present invention is applied can automatically perform such time correction processing even when connected to an external device or network for purposes other than time correction. This means that it is possible to execute the time correction processing without reducing the operation burden on the user and without being affected by the radio wave condition or the region.

  For example, when performing a correction process taking into account the time zone, the user can easily recognize the local time of the region where the user is present together with the clock without performing any special operation on the clock (for example, on the clock). The displayed local time can be visually confirmed).

  Specifically, for example, when traveling across time zones, the user needs to perform an operation for correcting and setting the time by himself / herself when he / she brings a conventional clock. On the other hand, by bringing a watch to which the present invention is applied, the user simply performs a simple operation such as USB or Internet connection without performing any such special operation (in addition, If you use the IPv6 wireless function described above, you can easily recognize the local time in the area where you are located without any operation.

  Furthermore, when a user lives in an area where standard radio wave reception is poor, or when only one radio wave transmission station is suspended for a long time, the conventional clock has a so-called “radio clock” function. Even if it is installed, the function cannot be used, and the clock cannot be automatically corrected. As a result, there is a problem that the time is distorted. However, by using a timepiece to which the present invention is applied, it is possible to correct the time automatically by solving such a problem, that is, by establishing a network connection means (chargeable).

  By the way, the series of processes described above may be executed by software as described above, or may be executed by hardware.

  When the above-described series of processing is executed by software, a program constituting the software is stored in a computer (including the electronic timepiece 1 and the electronic timepiece 61) incorporated in dedicated hardware, or various kinds of processing. By installing the program, the computer may be installed from a network or a recording medium on a computer capable of executing various functions, for example, a general-purpose personal computer.

  FIG. 17 is a block diagram showing an example of the configuration of a personal computer that executes the above-described series of processing by a program.

  In FIG. 17, a CPU (Central Processing Unit) 201 executes various processes according to a program stored in a ROM (Read Only Memory) 202 or a storage unit 208. A RAM (Random Access Memory) 203 appropriately stores programs executed by the CPU 201 and data. The CPU 201, ROM 202, and RAM 203 are connected to each other via a bus 204.

  An input / output interface 205 is also connected to the CPU 201 via the bus 204. Connected to the input / output interface 205 are an input unit 206 composed of a keyboard, mouse, microphone, and the like, and an output unit 207 composed of a display, a speaker, and the like. The CPU 201 executes various processes in response to commands input from the input unit 206. Then, the CPU 201 outputs the processing result to the output unit 207.

  Further, the CPU 201 has a clock inside, and can also perform a time counting operation using the clock.

  The storage unit 208 connected to the input / output interface 205 includes, for example, a hard disk, and stores programs executed by the CPU 201 and various data.
