The present invention is a novel method and apparatus for implementing a high-precision timer utilizing a non-optimal oscillator and a high-speed oscillator wherein only one oscillator is enabled at a given moment in time. The high-precision timer method and apparatus comprises a timer and an error-correction technique. In one embodiment, the timer of the present invention is constructed from a high-speed oscillator and a low-speed non-optimal oscillator. The timer operates from the high-speed oscillator during on-the-air modes of operation and from the low-speed non-optimal oscillator during sleep modes of operation. The present inventive method corrects errors that are introduced by the non-optimal oscillator and a swallow counter. The errors are corrected using an error-correction technique having two steps: an error-determination step and an error-correction step. In the preferred embodiment of the error-determination step, a total error for a time interval is determined by performing the following steps: (1) calculating an individual error that occurs at each pulse; (2) multiplying the individual error by the number of pulses occurring during the time interval; and (3) adjusting for a non-optimal counter. Once an error has been determined, the error-correction step adjusts a clock counter accordingly. Depending upon the error-correction technique used, the error-correction step can correct the total error at one of several locations within a timer counter chain that is used to practice the present invention. The implementation of the present invention allows a straightforward realization of multiple timers.
