To enable/disable and start/stop a service simultaneously, combine the command with the --now switch: If the service unit file is not located within one of the known systemd file paths, you can provide a file path to the service unit file you wish to enable: However, this file needs to be accessible by systemd at startup. After the initial time sync, Chrony never steps the clock. Chrony is a newer implementation of the NTP that usually updates time faster and is more accurate than ntpd. makestep Microsoft Azure joins Collectives on Stack Overflow. Chrony synchronize the system clocks time faster and with better accuracy than the ntp. For example, if chrony.conf had makestep 1 3 the clock would be stepped in the first three updates if its offset was larger than one second.
