However, the present invention is not limited to such an example, and the communication terminal device A is not limited to such an example. May be connected via a.

FIG. 2 shows a communication terminal device A and a time server B
FIG. 2 is a conceptual diagram of a system showing a relationship with the system. Time server B that can be accessed and used from the communication terminal device A of the present invention
There are SNTP server, NTP server, etc.
Reference time data measured using an atomic clock, GPS, or the like is held in real time with accurate accuracy. The communication terminal A accesses the time server B via the Internet, and sends a predetermined protocol signal from the communication terminal A to request the reference time data. Since it has been
The signal processing unit 1 performs a predetermined calculation based on the reference time data, calculates the correct year, month, day, and current time of the place where the communication terminal device is installed, and converts the time data of the clock circuit 11 Fix it.

Next, the operation of correcting the time data of the clock circuit in the communication terminal device A of the present invention will be described. Steps 100 to 105 in FIG. 3 show the basic procedure of the operation of correcting the time data of the clock circuit. Here, if the operator performs a predetermined operation, the signal processing unit 1 determines this, accesses the time server B, receives the reference time data, and calculates the time data of the clock circuit 11. I have.

An outline of the basic operation procedure is as follows.
By operating a time adjustment key 5A provided on the operation panel or a predetermined function key (not shown), the signal processing unit 1 determines this as a time adjustment command,
The dial number of the access point of the provider and the login information are read from the login basic setting information memory 10, and a dial signal is transmitted from the interface 2 to call the provider.

When the provider accepts the call, it sends out information necessary for login, accesses the time server B after connecting to the network, and requests reference time data. On the other hand, since the time server B transmits the reference time data, when the interface 2 receives the reference time data, the signal processing unit starts up the program stored in the ROM 6 and based on the received reference time data. , And correct time data to be measured in the clock circuit 11 is calculated. This time data is supplied to the clock circuit 11
Calculates the current time to be measured. The year, month, day, and current time are calculated, and the time data of the clock circuit 11 is rewritten.

According to such a communication terminal device A, when the operator operates a predetermined time adjustment key 5A or the like provided in advance, the signal processing section 1 accesses the time server B to access the reference time data. And the clock circuit 11
Can be corrected. FIG. 4 shows a basic operation for automatically correcting the time data of the clock circuit by repeatedly accessing the time server at a predetermined time set in advance.

This basic operation combines a time check mode as shown in FIG. 4A and an automatic time adjustment mode as shown in FIG. 4B. The access time to the time server can be set every morning, at the beginning of every month, or at predetermined intervals from the initial setting. This communication terminal device A
In the time check mode, as shown in steps 200 to 201 in FIG. 4A, the signal processing unit 1 always refers to the clock circuit 11 and reaches a preset time, or the time elapses. If so, set the flag.

In the automatic time adjustment mode, as shown in steps 300 to 306 in FIG. 4B, if a flag is set, the signal processing unit 1 determines this and the login basic setting information memory 10 Read out the dial number and login information of the provider's access point,
A dial signal is transmitted from the interface 2 and a call is made to the provider. If the provider receives a call, the login information is transmitted and the time server B is connected to the network.
To access.

When the reference time data is received from the time server B, the signal processing unit 1 calculates time data to be measured in the clock circuit 11 based on the reference time data, and calculates the calculated time. The data is written to the clock circuit 11 and the flag is cleared. The communication terminal device A automatically accesses the time server B and receives the reference time data at the set time, so that the time data of the clock circuit 11 can be corrected without any trouble.

When a connection is made with a provider for sending and receiving electronic mail and browsing, the time server B may be accessed together with sending and receiving electronic mail and browsing. In such a case, the time data of the clock circuit 11 can be automatically corrected without paying any attention to the time server B. Access to the time server B is completed in a short time, so that transmission and reception of e-mail and browsing are not hindered.

FIG. 5 shows an example of this operation. FIG.
In the example, the time server B is accessed when the flag shown in FIG. 4A is set. That is, after the set time, when accessing the provider for the first time, the time server B is accessed. Further, in FIG. 5, after the time server B is accessed, processing such as transmission / reception of an e-mail is performed. The server B may be accessed.

[0021]

As can be understood from the above description, according to the communication terminal device of the first aspect, when the time server is accessed and the reference time data is received from the time server, the reference time data is transmitted. The time data of the clock circuit can be automatically calculated and corrected based on the
Therefore, the time data of the clock circuit can be easily and accurately obtained.

According to the second aspect, when the operator performs a predetermined operation, the time server can be accessed to correct the time data of the clock circuit. Further, according to claim 3,
Since the time server is repeatedly accessed at predetermined time intervals, the time data of the clock circuit can be automatically corrected without requiring an operator's operation.
