TIMEPIECE APPARATUS TO CHANGE TIME INTO ON-THE-SPOT TIME ACCORDING TO TIME DIFFERENCE ZONE

摘要

The device for displaying a local time with one button pressure is accomplished by calling one of twenty-four local area time data stored in the internal memory, each having one hour time difference. The device comprises: a button switch handler (1) provided with button switches (1A) to input a wanted area code; an input data latch (2) for latching a switch input signal and transferring to the microprocessor (4); a memory (3) having time conversion data; a microprocessor unit (4) for computing a local time; a counter to supply a clock count value to the microprocessor (4); and a crystal (7).
