Why is chrony not synchronizing?
3 Answers. “The server is ignored for synchronization of the clock because it’s too inaccurate. In the “chronyc sources” output there is “+/- 4695ms”, which is larger than the default maxdistance of 3 seconds. The maxdistance option was added in chrony-2.2, so that’s why it worked with chrony-2.1.

How to use Chrony as a time server?
With chrony suite you can synchronize the system clock with an external time server using the Network Time Protocol (NTP). In RHEL 7 there is a choice between the daemons ntpd and chronyd, available from the repositories in the ntp and chrony packages respectively.
