A method and system for network terminal clock synchronization includes determining a respective round trip delay time from a master terminal to each slave terminal and offsetting the clock of each slave terminal by an amount proportional to the respective determined round trip delay time such that the master terminal and each of the slave terminals have substantially the same point of reference in time. The method and system further include, in response to a trigger signal, determining a respective offset between the master clock of the master terminal and the clocks of each of the slave terminals and offsetting the clocks of each of the slave terminals by an amount proportional to the determined respective offset to synchronize the clocks of each of the slave terminals to the master clock of the master terminal.
