ABSTRACT:
A time correction system has a timepiece with pointers for displaying the time, and a correction instruction device. The correction instruction device has a timing section for timing reference time data, a time input section for inputting pointed time data corresponding to the time indicated by the pointers, a comparison section for comparing the reference time data and the pointed time data, and a communication section for outputting a correction instruction signal based on the results of this comparison to the pointer type timepiece. The pointer type timepiece has an external signal detection circuit for receiving the correction instruction signal, a drive control section for controlling the driving of the pointers, and a time correction control circuit for matching the readings of the pointers with the reference time data based on the received correction instruction signal.
