Clock seems to be better than ntpd. It can complete forced time synchronization when the time error is large, but ntpd is difficult to do it, and clock has faster convergence speed than ntp

Chronyd seems to be better than ntpd. When the time error is large, it can complete forced time synchronization, but ntpd is difficult to do it, and the Chronyd convergence speed is faster than ntp
