Abstract: This application discloses a TSN time synchronization method and apparatus. One example method includes: a first apparatus receives a first TSN time synchronization message from a second apparatus; the first apparatus determines that the first TSN time synchronization message does not carry a first time, where the first time is a system time of a wireless communication system when the second apparatus receives the first TSN time synchronization message; and the first apparatus locally obtains a bridge residence time, write the bridge residence time into the first TSN time synchronization message, and send the first TSN time synchronization message.
