Abstract
In a time synchronization method, after clock board times between service boards are synchronized, a service board obtains a CPU time and the clock board time of the service board according to a preset periodicity, and makes a record. When performing CPU time synchronization between the service boards, the service board obtains a current CPU time of the service board, calculates a synchronization time of the CPU based on the current CPU time, a last recorded CPU time and clock board time, and adjusts the CPU time of the service board to the synchronization time. After the clock board times between the service boards that need to implement CPU high-precision time synchronization are synchronized by using a high-precision time synchronization protocol, the CPU time of each service board is adjusted to a corresponding synchronization time.
