Abstract

A register having a predetermined set value is provided in parallel with a counter for counting a basic signal generated from a crystal oscillator. The register and the counter are connected to a comparator for inputting a count signal into a time-counting circuit every time when the count value of the basic signal in the counter has reached the set value in the register. A signal based on the time-counting signal is sent from the time-counting circuit to a display which indicates time based on the signal. The time indicated on the display is compared with the standard time indicated by a television or the like. In this case, when there is a time difference between the display time and the standard time, a correction value, in terms of the number of seconds, corresponding to the time difference is input through an input unit. The input correction value is calculated in a computing circuit, and is set as a new set value in the register. A time-counting signal based on the newly set value in the register is output from the comparator. This improves the accuracy of the time indicated on the display.
