DAYLIGHT SAVING TIME ADJUSTMENT METHOD AND TIMEPIECE EMPLOYING THE METHOD

摘要

Used in an analog timepiece, a daylight saving time adjustment method is disclosed to includes the steps of: (a) use a time setting device to input date and time data and an adjustment knob to the adjust the hour and minute hands to 12:00, (b) use setting and selection buttons of the time setting device to adjust polarity relationship between stator and rotor of a driving unit for the rotor to move a gearwheel set and to further adjust the second hand to 12:00, (c) the CPU of the analog timepiece analyzes the inputted data subject to calculation of its built-in daylight saving time calculation program, and then drives the driving unit to move the hour and minute hands to indicate the local standard time subject to the inputted data if the inputted data was inputted before start of daylight saving time, or to indicate the corrected local daylight saving time if the inputted data was inputted after start of daylight saving time, and (d) CPU drives the driving unit to move the hands set, returning the analog timepiece from the daylight saving time to the standard time.
