Title:

TIME SYNCHRONIZATION NETWORK

Document Type and Number:

WIPO Patent Application WO/2022/009724

Kind Code:

A1

Abstract:

Provided is a time synchronization network in which it possible to efficiently maintain time synchronization according to absolute time.　A communication device (11) is provided with a time information output means (120) for outputting time information according to an internal clock (121) that is stable, and a time synchronization means (111) for correcting the time information of the time information output means (120) on the basis of time difference information between the communication device (11) and a communication device adjacent to the communication device (11).
