Abstract
A time synchronization method for a time synchronization device, wherein the device is connected to a plurality of time synchronization domains through a plurality of ports, and the plurality of time synchronization domains use a plurality of PTP profiles. The method comprises determining whether each of the plurality of ports is a time receiving port or a time transmitting port; obtaining information of a grandmaster clock of the plurality of time synchronization domains; performing information conversion on the information of the grandmaster clock according to a PTP profile corresponding to each time transmitting port of the plurality of ports in the plurality of PTP profiles, so as to generate a plurality of clock information corresponding to each time transmitting port; and transmitting a corresponding clock information of the plurality of clock information to a corresponding time synchronization domain from each time transmitting port, so as to perform time synchronization.
