A time synchronization method for a time synchronization device is provided. The time synchronization device connects a plurality of time synchronization domains through a plurality of ports, and the plurality of time synchronization domains complies with a plurality of PTP profiles respectively. The time synchronization method includes determining each port of the plurality of ports to be a time receiving port or a time transmitting port; obtaining information of a grandmaster clock (GM) in the plurality of time synchronization domains; converting the information of the GM to generate a plurality of clock information corresponding to each time transmitting port of the plurality of ports according to the PTP profile of the plurality of PTP profiles corresponding to the each time transmitting port of the plurality of ports; and transmitting a corresponding clock information among the plurality of clock information to a corresponding time synchronization domain by each time transmitting port for time synchroniz
