Abstract

A method for clock synchronization includes computing an offset value between a local clock time of a real-time clock circuit and a reference clock time, and loading the offset value into a register that is associated with the real-time clock circuit. The local clock time is then summed with the value in the register so as to give an adjusted value of the local clock time that is synchronized with the reference clock.
