PROBLEM TO BE SOLVED: To reduce a processing load on a slave node and also to reduce a network load concerning a clock synchronization system for clock synchronization between a master node and the slave node which are connected via a network.SOLUTION: The clock synchronization system includes a plurality of master nodes and the slave node for performing clock synchronization with one of the master nodes. The first master node performing clock synchronization with the slave node between the master nodes compares synchronization precision in the second master node between the master nodes with the own synchronization precision, so as to indicate the second master node and the slave node to perform clock synchronization between the second master node and the slave node when the synchronization precision of the second master node is more excellent than the own synchronization precision, and to continue clock synchronization with the slave node in the other cases. |
