COMPUTING EQUIPMENT AND METHODS FOR DETECTING AND RECOVERING TIMER ERRORS

Abstract

The invention relates to a computing device and method for detecting and recovering from timer errors. The device may include running multiple timers in parallel, including a first active timer, a first supervisory timer, and a second supervisory timer, each with its own independent time base; determining whether the first of the multiple timers is faulty; discarding the first timer when it is determined that the first timer is faulty; determining whether the first timer has a consistent time base difference independent of the second of the multiple timers; and bringing the timer back into service with time adjustments in response to the determination that the first timer has a consistent time base difference independent of the second timer.
