If it has not been updated, the second hand counter C60S is incremented (steps G960, G970).

(8) If the minute hand has been updated in the determination in step G960, the second hand of the clock CK3 of its own device is adjusted by the amount of the time correction value HOTIM, and the second hand counter C60S is reset (steps G965 and G975).

(9) Next, it is determined whether or not the correction completion time has elapsed by the value of the counter AJTC counter which is set at the start of the correction and which counts down every second. The correction completion time has elapsed. If so, the correction completion flag AJENDF is turned on, that is, "FFFF", and the correction flag AJTF of the clock CK3 is cleared (steps G980 and G985).

(10) If it is determined in step G980 that the correction completion time has not elapsed, the correction completion flag AJEN
DF is cleared and the correction completion counter is incremented (step G990).

(11) Next, the correction completion flag AJENDF
Value is judged, and if it is ON, the clock CK of its own device
Assuming that the clock setting of 3 is completed, the time correction value HOTI
The process is terminated by setting M to "0" and the minute hand update period H60S to 60 seconds, and returns to the main routine (step G995,
G997).
