Estimating the term…
The present disclosure relates to a time control device, a time control method, and a program that can synchronize time information with a master device in a network with high precision. The time control device as one aspect of the present disclosure includes: a first calculating unit that calculates a first time difference based on the transmission times and the reception times of messages exchanged with the master device, the first time difference indicating a difference between time information about the master device and time information about the slave device; a second calculating unit that calculates a second time difference based on the transmission time and the reception time of the message transmitted from the master device to the slave device; a third calculating unit that calculates a third time difference based on the transmission time and the reception time of the message transmitted from the slave device to the master device; and an adjusting unit that adjusts the time information about the slave device in accordance with a feedback control value generated based on a selected one of the first through third time differences. The present disclosure can be applied to a PTP slave, for example.
A time control device that is installed in a slave device, and synchronizes time information with a master device to which the slave device is connected via a network,
A time control method implemented in a time control device that is installed in a slave device, and synchronizes time information with a master device to which the slave device is connected via a network,
A program to be executed by a computer that is installed in a slave device, and synchronizes time information with a master device to which the slave device is connected via a network,
