Drift compensation for a real time clock circuit

Implementations of the present disclosure involve an apparatus and/or method for adjusting a counter in a computing system to account for drift of the counter value over time compared to another counter of the system. In particular, a processor of the computing system that includes a local counter component may access a counter component of another processor of the system, referred to as the reference counter. By comparing the value of the reference counter to the local counter, the processor may determine any drift that may have occurred over a period of time in the local counter. The calculated drift, or counter error, may be converted into one or more adjustments to the local counter to synchronize the local counter with the reference counter. In one embodiment, the adjustment to the local counter includes increasing the rate at which the local counter is incremented for a period of time.
