Abstract

PURPOSE:To enable the time difference from the set time to be digitally displayed by storing the time set from the outside and counting the difference between that time and the time at the present moment. CONSTITUTION:The desired time is stored and set in a memory device 8 by introducing pulses of second unit from an oscillator by closing a switch 10. At the above setting, a decoder 4' is changed over and connected to the memory device 8 and setting is performed while the contents of the memory device 8 are being displayed in a display part 6'. When the desired time is displayed, the switch 10 is opened, then the desired time is set in the memory device 8. Next, an auxiliary counter 9 is normally counting the time difference until the time of the clock counter 3 counting the current time reaches the time of the memory device 8. When the decoder 4' is changed over and connected, said time difference may be displayed in the display part 6'.
