The invention relates to the technical field of clock synchronization, in particular to a clock synchronization method and system of a wired-wireless hybrid TSN architecture. According to the clock synchronization method, after a PTP slave device module obtains reference clock information of a GMC highest-level clock, clock information of the PTP slave device module is calibrated according to reference timestamp information of the reference clock information so as to generate synchronous clock information, and the synchronous clock information comprises synchronous timestamp information; the synchronization timestamp information is sent out in a wireless mode and a wired mode through the clock domain conversion module, so that the first external terminal receiving the synchronization timestamp information in the wireless mode and the second external terminal receiving the synchronization timestamp information in the wired mode can perform clock synchronization according to the synchronization timestamp inform
