Description:
chrony is a daemon which implements the Network Time Protocol (NTP) and is designed to synchronize system clocks across a variety of systems and use a source that is highly accurate.
chrony can be configured to be a client and/or a server.

If chrony is in use on the system proper configuration is vital to ensuring time synchronization is working properly.
Note:
This recommendation only applies if chrony is in use on the system.
Remediation:
Add or edit server or pool lines to /etc/chrony.conf as appropriate:
server
Add or edit the OPTIONS in /etc/sysconfig/chronyd to include '-u chrony
OPTIONS="-u chrony"
Parameter:
[2.rhel.pool.ntp.org]
