PROBLEM TO BE SOLVED: To automatically correct times of plural devices connected to a network, and to precisely conduct time synchronization among the devices. SOLUTION: A GPS receiver 13 receives a time signal from a GPS satellite 11 via an antenna 12. The receiver 13 is connected to terminals 15-1-15-n via the network 14, a time data is transmitted to the terminals 15-1-15-n connected directly to the network 14 in the condition where the time data is received at the same time, based on the time signal received from the satellite 11, and the times in the terminals 15-1-15-n are synchronized highly precisely with respect to the present time. |
