PURPOSE:To make possible the automatic correction of calender display along with time differential correction by cooperating a correcting minute input means, addition-subtraction correcting means of the digits of the hour and calendar correcting mechanism. CONSTITUTION:Each time when a button S1 is pushed, a correction symbol 14 is applied to the subtraction terminal of a time-calendar count decoder driver 3, by which the contents thereof are reduced and the numerical value of the digits of the hour of a display device 4 is reduced. On the other hand, when the time corrected by the calendar correction mechanism cooperating with this time correction passes 0:00 AM, the calendar display in the display device 4 is corrected. Hence, when the time differential correction is performd, the necessary calendar correction is automatically accomplished and displayed. The similar results may also be obtained even if addition is used in combination in the digit correction of the hour. |
