TW200702958A - Movement of timer capable of automatically adjusting daylight saving time - Google Patents

Abstract

This invention disclosed the movement of a timer capable of automatically adjusting the setting of daylight saving time. This technique is mainly to install a CPU onto the movement of the timer. The CPU is equipped with at least one perpetual calendar and an operation program that can calculate time differences and daylight saving time. There is a set of mode-adjusting buttons used to perform initial setting whose zero point is set at the position of 12 o'clock and to set correct time comprising year, month, date, hour, minute, and second. Besides, there is a time-zone-adjusting device used to input the signals of different time zones into the CPU. After the setting of the movement is done, the timer can command the CPU to receive the time zone signal and calculate whether daylight saving time is used in order to automatically display the correct time of the selected time zone from the time-zone-adjusting device of a time-displaying device. This method can facilitate a user to adjust setting at one time, which makes the timer quickly and automatically display relatively correct time including daylight saving time. The installed time-calculating program can not only automatically calculate whether daylight saving time is used, but also automatically adjust the movement by the driving signal of correct date and time, and manual adjustment is not required.
