WebFeb 21, 2024 · In addition to the "unreliable network" operation, chrony can make a larger correction to the system clock frequency. If the difference between nominal clock frequency and observed clock frequency is more than ±500 parts per million, ntpd will not correct it. Basically, chrony works better in a virtual machine than ntpd. – Chad Farmer
