PROBLEM TO BE SOLVED: To provide a time synchronization system employing a plurality of networks that makes appropriate time correction even immediately after the network switchover.SOLUTION: A time synchronization system where a time master, a time slave, and a management node are connected via a plurality of networks is characterized in that, if the management node determines switchover of a network for transmitting time packets, the management node communicates information that identifies the switchover target network to the time slave. |
