Document Type and Number:
WIPO Patent Application WO/2021/014614
Kind Code:
A1
Abstract:
In this time synchronization device (10), a time acquisition unit (21) acquires an external time that is the time of an external watch (51) from a time distribution device (50). An internal time setting unit (22) transmits the external time acquired by the time acquisition unit (21) to a time conversion device (40). A time conversion unit (26) converts the external time into an inherent time that is a time within a management range of the internal watch (14). The internal time setting unit (22) sets the inherent time, acquired by being converted by the time conversion unit (26), for the internal watch (14).
