Abstract
PURPOSE: To eliminate trouble in setting time of a timepiece by using the broadcast time signal to correct time automatically as well as provide a warning when correction is impossible.
CONSTITUTION: The time difference between the hour output or minute signal 1 of a timepiece and a selected broadcast time signal 2 is counted 6 and at the same time, whether the timepiece is fast or slow with respect to the broadcast time signal 2 is decided 4 and stored 5. When the timepiece is fast; it is stopped to correct time, the counter is made to subtract or the governor is corrected in the slow direction. On the other hand, when the timepiece is slow, the opposite operation is performed. When the time signal 2 and the hour signal or minute signal 1 exactly coincide with each other, the operation of the time-correcting apparatus is inhibited 3. When the gaining or losing amount exceeds the correctable limits, a gain-loss warning 7 is provided.
