The extension telephones 5-1 to 5-n are connected to each other via telephone lines 1 to 4-n, and a switchboard (relay board) 7 is connected to each other via a switchboard circuit 6. The operation of the switching circuit 1 is controlled by a control device 8 which issues commands according to a call processing operation management program. This control device 8 includes a storage device 9, a maintenance terminal 10 for setting telephone numbers, etc. An external clock (with clock display device 11 and power supplies for
It sends and receives signals to and from the system clock (hereinafter referred to as the hard clock) 12, and also controls the count of the software clock function (hereinafter referred to as the system clock) 13 on the software, and displays the time on the system clock 13 on the clock display. It is displayed on 11. Note that this system clock 13 is for controlling the execution time of the call processing program in the control device 8, and the time must be accurate and highly accurate.

By the way, when the power supply to the electronic exchange is stopped, the function of the system clock 13 is also stopped at the same time. Therefore, when the power supply is restored, the time of the system clock 13 is adjusted using the time of the node clock 12.

Therefore, the times of the node clock 12 and the system clock 13 must always match. However, no--
Clock 12 is your own internal clock! The system clock 1 is a function that calculates the time by counting
Number 3 has a function that calculates the time by counting the clocks, lights, and clocks of an electronic exchange, and each counting function is completely different. For this reason, each clock 1
The times at 2°13 do not match, and it is necessary to adjust the time.

Then, the adjustment time 1j data from the maintenance terminal 10 (
If it is determined that the change should be made, the time data for changing the year, month, and day are sent to the system clock 13 and the node clock 12. to change the year, month, and day. After k Q,
The year, month, and day of the system clock 13 are read and displayed on the clock display device 11.

After this change, or after you decide not to make the change,
The current hour, minute, and second data is read from the system clock 13 and displayed on the time display device 1 at 9 seconds. And time,
It is determined whether to change the minutes and seconds, and if it is determined that the changes are to be made, the time data for changing the hours, minutes, and seconds is sent to the system clock 13 and the hardware time Z↑12: and the changes are made.
The hours, minutes, and seconds of the changed system clock 13 are read and displayed on the clock display device 1.

Next, after this change or after determining that the hours and minutes and seconds are not to be changed, the current day of the week is read from the system clock 13 and displayed on the clock display device 1. Then, it is determined whether or not to change the day of the week, and if it is determined to be changed, the time r-evening for changing every other day is sent to the system clock 13 and the hard clock 12 to change it, and the changed day of the week is displayed on the clock. Display it on device 1.

As described above, the time adjustment between the hard clock 12 and the system clock 13 is completed. In addition, when there is a request for clock adjustment from the switchboard 7, time data for change is received from the switchboard 7, and each time is adjusted by the same operation as in the case of the maintenance terminal 10. In this case, first the year,
Change the month and day, then the hour, minutes, and seconds.
Either the day of the week cannot be changed, or the day of the week can be changed by adding a program.
