Abstract

PURPOSE:To make it possible to display the time of the desired area stored in memory means by providing area memory means for selectively storing a desired number of areas of plural areas and by operating a single outside switch. CONSTITUTION:A switch 8 is operated to select the desired city from the various cities in the world, which are displayed in a city display unit 5, and stores it in advance in a city memory unit 10. This memory is accomplished by shifting the content of a shift resistor 7 under the condition leaving a comparator unit 11 inoperative. In case the comparator unit 11 is operated, the content of the shift resistor 7 is compared with that of the memory unit 10 at the comparator unit 11 by the operations of the switch 8. Until the both become coincident, the contents of the shift resistor 7 are sequantially shifted, and the contents of the time counting circuit 3 are added by + one hour. In accordance with the contents of the shift resistor 7, the desired city is displayed in the display unit 5, and the time of the city is displayed in its display unit 4.
