WIPO Patent Application WO/2020/054219
Kind Code:
A1
Abstract:
The present invention performs synchronization on a plurality of communication devices connected through communication while flexibly coping with a change in a communication state. A time management unit manages a time. A time measurement unit measures a time of another time management unit and a time of this time management unit for each prescribed process in a communication process with another device having the other time management unit. A time difference generation unit generates, on the basis of the measured times, the time difference between the time of the other time management unit and the time of this time management unit. A time correction instructing unit instructs the other device to correct the time of the other time management unit on the basis of the generated time difference.
