Abstract

PURPOSE: To simplify the time correction, by keeping the time difference between the present time and another time, through the simultaneous correction of minute correction of the present time and another time.
CONSTITUTION: The present time system 1 and another time system 2 have respectively minute counters M1, M2, and hour counters H1, H2, and the coincidence detection system consists of the minute comparison circuit CM and the hour comparison circuit CH. Further, with the minute correction mode signal MS at H level, when the correction signal SET is inputted to M1 and M2, if M1 has hour carry signal HOUR, the signal f512 is inputted to H2 to perform carry. Thus, the delay by one hour in another system 2 is avoided to keep the time difference between the both as first.
