ABSTRACT:
A method of keeping global time in a wireless network, the method includes reading a Time Synchronization Function (TSF) to provide an initial time base. An interconnected clock control circuit is employed to read the TSF time from the circuitry used to read the TSF and to implement a local clock based on time values read from the TSF.
