####What's the maximum tolerance for time synchronization error of PD?
Theoretically, the smaller the time synchronization error, the better. PD can tolerate any synchronization error, but a larger error value means a longer period of service stop during the leader change. If the clock goes back during a leader change, the change process will not proceed until it catches up with the previous leader.
PD can tolerate any synchronization error, but a larger error value means a larger gap between the timestamp allocated by the PD and the physical time, which will affect functions such as read of historical versions.
