DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a time information correcting device for correcting and adjusting the time of a clock device in an electronic exchange accommodating an outside line, an extension line, a dedicated line and an extension telephone.

[0002]

2. Description of the Related Art Conventionally, in an electronic exchange or the like accommodating an external line, a dedicated line, and an extension telephone, for example, a transmission / reception time of a facsimile message is entered and a current facsimile message is automatically transmitted at a designated time. A clock device that measures the time is provided. The time here is corrected to match the delay or advance. As a conventional example of providing a clock device in such an electronic exchange and correcting the clock device,
Japanese Patent Application Laid-Open No. 61-99491 discloses a technique of "a clock adjusting device for an electronic exchange". In this conventional example, a control terminal is instructed from a maintenance terminal to set or change the transmission time, and to perform correction for adjusting the time delay or advance.

FIG. 4 is a block diagram showing a configuration of a conventional time setting device provided in an electronic exchange or the like.
5 is a flowchart showing a processing procedure of the time setting. 4 and 5, when the time is set from the input device 1 such as a maintenance terminal in the electronic exchange, the time setting command is input to the control device 2.

In the control device 2, the command analysis unit 2a analyzes the input command (steps S1, S1 in FIG. 5).
S2). If the time is not set (No), processing other than the time setting is executed according to the command, and the process ends. If the result of the analysis in steps S1 and S2 indicates that the time is set (Yes), the time setting unit 2b outputs the time information in the time setting command to the clock device 4 to the clock device 4 (step S4). The clock device 4 that has received the time information performs time setting to correct and adjust a delay or advance with respect to the current time based on the time information (step S5).

[0005] In such time setting, when the amount of control processing in the control device 2 is large, the time setting command input from the input device 1 is used based on the influence of the waiting time in interrupt processing other than the time setting. The time until the clock device 4 actually performs the time correction varies. In other words, there may be a few seconds error in the time setting. In this case,
Time setting work must be performed again.

[0006]

As described above, in the above-described conventional example, the time required for the clock device 4 to perform the time correction varies, so that the time setting work needs to be performed again. , The time of the control process fluctuates, and it is difficult to set an accurate time. That is, the control device 2 performs various types of processing in addition to the time setting processing, and the time of the time correction varies due to execution of the interrupt processing.
Further, there is a disadvantage that time setting work must be performed again, and it takes time and effort to set the time precisely to the actual time.

[0007] The present invention is intended to solve the problems in the conventional art, when the time setting in the clock device in an electronic exchange, providing the time information correction apparatus time-setting of the correction can be performed accurately and easily With the goal.
