A multi-synchronization-domain time synchronization system, a multi-synchronization-domain time synchronization method and a cross-domain device. The method comprises: dividing a time synchronization network into a plurality of synchronization domains, deploying a cross-domain device between the synchronization domains, establishing a synchronization relationship between the synchronization domains through the cross-domain device, performing time source information transfer and time source protection between the synchronization domains, and implementing time synchronization between the synchronization domains. |
