Time synchronization cooperative control method, device and system and electronic equipment

The invention discloses a time synchronization cooperative control method, device and system and electronic equipment. The system is characterized in that a cooperative controller responds to a time synchronization request, acquires slave clock information and progenitor clock information, calculates an inter-domain time synchronization path between a progenitor clock and a slave clock, and issues the inter-domain time synchronization path to a domain controller; the domain controller plans an intra-domain time synchronization path; when time synchronization begins, the progenitor clock and the slave clock exchange timestamp information through network element nodes of the heterogeneous multi-domain network; the heterogeneous multi-domain network forwards the timestamp information of the progenitor clock through the network element nodes on the intra-domain time synchronization path, records the timestamp information received and sent by each network element node in the forwarding process, and reports the rec
