Abstract: [Problem] To reduce a total equipment cost. [Solution] A local device (20A) of a time synchronization system (10A) includes a path switching unit (33) that connects respective remote devices (40A1 to 40An) using individual optical fibers (60a to 60n) and switches the respective optical fibers (60a to 60n) sequentially in a cyclic order, a counter unit (31), a phase difference memory unit (30), and a table unit (32).
