    en.wikipedia.org/wiki/Timing_synchronization...

    The TSF is based on a 1-MHz clock and "ticks" in microseconds. On a commercial level, industry vendors assume the 802.11 TSF's synchronization to be within 25 microseconds [ citation needed ] . Timing synchronization is achieved by stations periodically exchanging timing information through beacon frames.
