Abstract: Examples in this application include methods for sending accuracy information, example apparatuses, and systems. In one example method, a first network element switches from a locked state to a holdover state, and the first network element sends state information to a second network element. The state information includes accuracy information of the first network element in the holdover state. According to the foregoing method, the second network element may obtain state information of the first network element in the holdover state, and perform clock synchronization with the first network element or the second network element based on the state information.
