We present a detailled timed automata model of the clock synchronization algorithm that is currently being used in a wireless sensor network (WSN) that has been developed by the Dutch company Chess. Using the UPPAAL model checker, we establish that in certain cases a static, fully synchro-nized network may eventually become unsynchronized if the current algorithm is used, even in a setting with infinitesimal clock drifts. 1
