PURPOSE:To simplify an operating method, by providing a first switch switching an ordinary time-displaying state and a time-correctable state selectively, and second and third switches conducting incremental/decremental correction for a regional zone in a state wherein a time is displayed. CONSTITUTION:When a switch 10 is turned ON in a state wherein a time display unit 6 displays a time, time counters in a regional zone counter 5 and a time counter 3 are incremented by +1 through a key input control circuit 8. The respective values of the counters are decoded by a display circuit 4, a lighting segment of a regional indicator 7 is shifted by one, and a time is advanced by 1hr. Incremental correction for a regional zone by the switch 10 is executed in the above-started way. As to a switch 11 likewise, each counter is decremented by -1 and decremental correction for the regional zone is executed. When a switch 9 is turned ON in the state wherein the time display unit 6 displays a time, the display is switched over to a time-correctable display through the circuit 8, the counter 3 and the circuit 4. Accordingly, an operating method can be simplified. |
