摘要： A time keeping system used to automatically adjust for daylight savings includes a processor having a preprogrammed internal clock module, a preprogrammed daylight savings time setting module, and a low power detection module. The preprogrammed internal clock module is programmed with a time, a date, and a year. The preprogrammed daylight savings time setting module is programmed with a plurality of daylight savings changes and automatically adjusts the internal clock to reflect a daylight savings time change. The low power detection module detects an operating power level. A primary battery is operatively coupled to the processor, and provides a primary power source to the processor. A frequency generating unit is also operatively coupled to the processor, and provides a frequency to the preprogrammed internal clock module. Furthermore, a clock movement unit is operatively coupled to the processor, and is configured to receive a series of timed-pulses from the processor.
