Abstract: A method for correlating first and second local time counts in first and second integrated circuits is provided. The first and second integrated circuits communicate via a communication network. A separate time control signal path is also provided between the integrated circuits. The method comprises determining a signal propagation latency associated with propagation of a latency determining signal between the integrated circuits on the time control signal path, and correlating the first and second local time counts in dependence on the signal propagation latency and a time correlating signal transmitted on the time control signal path.
