PROBLEM TO BE SOLVED: To provide a time synchronization device and the like that can improve time precision in communication by a particular protocol.SOLUTION: A packet filter processing unit 100 corrects packet transmission time (t1) on the basis of the minimum value (minimum PDV) of time difference (t2'-t1) between the packet transmission time (t1) from a time master apparatus 600 and packet reception time (t2') stamped by a first clock 250, and corrects packet reception time (t4) on the basis of the minimum value (minimum PDV) of time difference (t4-t3') between packet transmission time (t3') stamped by the first clock 250 and the packet reception time (t4) at the time master apparatus 600.SELECTED DRAWING: Figure 1 |
