Abstract
A time adjusting system for an electronic timepiece has a discriminating circuit for discriminating between an advanced signal appearing during the first 30 seconds of a minute and a delayed signal appearing during the latter 30 seconds of the minute. In the advanced state, the supply of 1 HZ pulses to the time-measuring device is temporarily stopped for a time equivalent to the duration of the advanced time thereby delaying the time. In the delayed state, time adjusting pulses higher in frequency than the 1 HZ pulses are supplied to the time-measuring device in a number equal to the duration of the delayed time thereby advancing the time.
