Abstract

PURPOSE:To perform time display correctly by so arranging a titled timepiece that the display chaning over of summer time and ordinary time is accomplished when the prescribed time is attained after a changeover means is operated. CONSTITUTION:When a switch 30 is closed in order to change the display of ordinary time to the display of summer time, the signal adding a 1 pulse signal 64 to the signal from a minute counter 6 is supplied to the phi input of a 24hr counter 10 at the 1st 0 o'clock in the morning, and a time display 22 is instantaneously displayed and changed over to 1 o'clock in the morning. To change over the display of summer time to the display of ordinary time, the switch 30 is opened, then the addition pulse of 1 pulse is applied to the counter 10 at the timing of the carrier signal 12 of the counter 10. At this time, the output of an FF92 becomes L and the counter 10 makes down counting once, by which the display is changed over to the ordinary time display with a one hour delay.
