Abstract
A fundamental interval of time is derived from a clock signal of an inherent frequency emanating from an untrimmed crystal oscillator. Firmware and hardware of the time-of-day clock system are used to control and modify the time interval between interrupt signals generated upon the occurrence of a specified count of clock cycles of the clock signals emanating from the crystal oscillator.
