Abstract
PURPOSE: To carry out automatically the clock rate adjustmetn by detecting error between a standard correct time and a watch correct time in a constant time unit and interrupting correction pulse into a frequency dividing circuit by means of an adding data of this error and the previous corrected amount or opening an interval.
CONSTITUTION: When receiver 6 a time informing sound, after is passes through a filter 7, a wave height is discriminated 8 and the time information pattern is discriminated 9. Then, when recognizing the time informing sound, a time correcting circuit 3 corrects a second pointer of a pointer display device 5 to a correct 0sec. Also, the counting equipment 11 counts difference days between the two time informations and detects the time difference between the value of the time counter 10 and a standard correct time pulse is detected 12 and divided by a value of the equipment 11 to be fed to an accumulator 13. The accumulator 13 adds the previous error data to an error data of this time and the value is introduced into a pulse number correcting circuit 14 to carry out the correct of the frequncy dividing circuit 2.
