Description

[Detailed Description of the Invention] [Summary] Correct time information is transferred from an exchange, the time of a clock function of a terminal device such as a telephone terminal device is corrected, the corrected time is displayed on a display section, and the correct time information is transferred to the terminal device. By setting time difference data and displaying the time corresponding to the time difference data on the display section, it is possible to easily know the time in the destination area when making a call to a foreign country or the like.

[Industrial application field]

The present invention relates to a terminal time display control system that allows a terminal device such as a telephone terminal device to display the time of a destination region such as a foreign country.

2. Description of the Related Art In terminal devices such as telephone terminal devices, a configuration is adopted in which a small display is provided to display the date, time, and the like.

[Conventional technology]

2. Description of the Related Art A terminal device such as a telephone terminal device equipped with a microprocessor is generally provided with a clock function and a display device to display the date and time.

In this case, if the time is displayed on the display using the unique clock function of each terminal device, the displayed time of each terminal device will differ due to the error.

Therefore, there is a method in which time information is periodically transferred from the highly accurate clock function of the exchange, the terminal device corrects the time of the clock function using that time information, and displays the corrected time of the clock function on the display. Proposed. According to this method, the display time of each terminal device can be adjusted to the standard time with a relatively small amount of communication.

[Problem that the invention seeks to solve]

As mentioned above, in the method of correcting the time of the terminal device's clock function using the time information from the exchange, the display time of each terminal device is set to the standard time, so it is possible to adjust the time between regions without time differences such as within Japan. When communicating with other countries, the time is the same in the destination area, so there is no particular problem, but when calling to areas with time differences such as foreign countries, 1. It is necessary to know the time in the other region. In that case, since only the standard time is displayed on the display of the terminal device, the time in the other party's area must be determined from a time difference table or the like.

In order to avoid such operations, it is possible to display the time in the other region on the display by giving the time difference to the clock function of the terminal device in advance. Since the time on the device's clock function was adjusted, it was not possible to display the time in the other region on the display.

SUMMARY OF THE INVENTION An object of the present invention is to make it possible to display the time of a partner region with a time difference with a simple configuration.

[Means for solving problems]

The terminal time display control method of the present invention allows time difference data to be set in the terminal device, and uses the time difference data to display the time of the other party's region on the display unit, and will be explained with reference to FIG. . The time information is transferred from the high-precision clock function 2 of the exchange 1 to the terminal device 3, the time of the clock function 4 of the terminal device 3 that received this time information is corrected, and the corrected time is added to the display section 5. The terminal device 3 is provided with a memory 6 for storing time difference data, and the time difference data set in the memory 6 by operating a function key or the like is added to the time display data from the clock function 4, and the display unit 3 displays the time. In addition to 5, the time is displayed according to the time difference data. Note that the memory 6 can adopt various configurations as long as it is a storage means that can set time difference data, and a partial area of the memory in the terminal device 3 can also be used.

[Effect]

By adding the displayed time data and the time difference data, the time difference is determined, and by displaying the time difference on the display unit 5, it is possible to easily know the time in the other party's area. Furthermore, if a plurality of types of time difference data are set in the memory 6 for storing time difference data, the display unit 5 can display the time according to the time difference of each region. Also, since the standard time can be displayed at all times, the time in the other region can also be displayed accurately.

15 is a general telephone line circuit (LC), 16 is an interface circuit (INF), 17 is a receiver (R), 18
is a driver (D), 19 is a terminal device, 20 is a general telephone circuit (TN), 21 is a handset, 22 is a driver (
D), 23 is a receiver (R), 24 is an interface circuit (INF), 25 is a terminal control unit (CTL) consisting of a microprocessor, etc., 26 is an interrupt timer (IRQ)
, 27 is a push button dial, 28 is a display such as a liquid crystal display,
29 is a registration key al, a time difference display key a2. 30 is a memory having a display time data area TD and time difference data areas TI and T2.

Network 11. Central control unit 12. Hard timer 1
3 and the terminal control line circuit 14, the exchange 1 shown in FIG. Also, the terminal control section 25, interrupt timer 26, and memory 3 of the terminal device 19
The clock function 4 is formed by o, the display part 5 is formed by the display 28, and the time difference data areas Tl and T2, which are part of the memory 30, form a memory 6 for storing time difference data.

The terminal control unit 25 receives an interrupt from the interrupt timer 26 at a fixed period (for example, 2m5) to display the display time data area TD.
The updated display time data is added to the display 28 and displayed. This interrupt timer 26
Since the accuracy of the clock function of the exchange is lower than that of the clock function of the exchange, the central control unit 12 of the exchange periodically transmits the time information of the hard timer 13 to the interface circuit 16.
, the time information is sent via the driver 18 and received by the terminal control unit 25 via the receiver 23° interface circuit 24. This time information is written as display time data in the display time data area of the memory 30, and from then on, , this display time data is updated every time there is an interrupt from the interrupt timer 26. Therefore, the standard time corrected by the highly accurate clock function of the exchange is displayed on the display 28.

To set the time difference data, for example, press the registration key a1 and input the time difference data from the push button dial 27. Since there is a time difference of -17 hours between Tokyo and San Francisco in the United States, input r*17J, for example. This time difference data is written to the time difference data area T1 of the memory 30. Next, when registering time difference data for New York, the time difference is −
14, so input "*14". This time difference data is written to the time difference data area T2 of the memory 30.

After setting the time difference data, press the time difference display key a2.
When you press , the terminal control unit 25 displays the display time data area TD.
Display time data is read from the time difference data area T1, time difference data is read from the time difference data area T1, and both are added. The addition result is displayed on the display 28 for a predetermined period of time (for example, 10 seconds). For example, as shown in FIG.
In the case of AM8: OIJ, if the time difference data in the time difference data area T1 is r-17J, adding the two results in 3:01 p.m., so the display shows rPM.
3:01J is displayed.

Similarly, when the time difference display key a3 is pressed, the New York time difference data r-14J is read out from the time difference data area T2, and when the displayed time data is shown in FIG. 3, the display shows rPM 6:OIJ. will be displayed.

By increasing the number of time difference display keys and creating corresponding time difference data areas in the memory 30 to set time difference data, time difference times around the world can be displayed in a simple manner.

The setting means in the above embodiment is the case where the registration key a1 and the push button dial 27 are used.
By dialing a special number from 7, the central control unit 12 of the exchange identifies the time difference data and notifies the terminal device 19 of the time difference data.
It is also possible to write to the time difference data area of the memory 30 under the control of. In this case, the registration key a1 can be omitted. It is also possible to transfer the time difference data to each terminal device from a maintenance console (not shown) or the like of the exchange and have it set.

In order to display the time difference, a special number is dialed from the push button dial 27, and in response to an instruction from the exchange that has identified this special number dial, the terminal control section 25 of the terminal device 19 displays the display time data and the time difference data in the memory 30. It is also possible to read out and add them, and display the addition result on the display 28. In this case, time difference display key a2. a3 can be omitted.

Further, after writing the time difference data to the time difference data area of the memory 30, when time information is transferred from the exchange, this time information and the time difference data are added to the display time data area T.
By writing in D and adding the contents to the display 28, the time difference can also be displayed. In this case, if the received time information and time difference data are controlled not to be added, the standard time will be displayed from the time the next time information is received.

For example, as shown in FIG. 4, if the time difference data of r-17J is set in the time difference data area of the memory, and the time information transferred from the exchange is rAM8:01J, this time information and the time difference data is added, and rPM3:OIJ is written in the display time data area as display time data.

The contents of this display time data area are added to the display to display the time difference, and the clock function of the terminal device 19 updates the contents of this display time data area by an interrupt from the interrupt timer 26 and continues. The time difference can be displayed on the display.

As mentioned above, by setting the time difference data of the destination region on a terminal device such as a telephone terminal device, the time difference can be displayed on the display 28 at all times or as needed. This means that it can be easily determined whether or not the time to transmit to the local area is appropriate.

[Effect of the invention] As explained above, the present invention provides clock function 2 of exchange 1.
