  We consider a stochastic model of clock synchronization in a wireless network
consisting of N sensors interacting with one dedicated accurate time server.
For large N we find an estimate of the final time sychronization error for
global and relative synchronization. Main results concern a behavior of the
network on different time scales $t=t_N \to \infty$, $N \to \infty$. We discuss
existence of phase transitions and find exact time scales on which an effective
clock synchronization of the system takes place.
