Ensure chrony is configured (Scored)

Level 1 - Server 
Level 1 - Workstation

chrony is a daemon which implements the Network Time Protocol (NTP) is designed to synchronize system clocks across a variety of systems and use a source that is highly accurate. More information on chrony can be found at http://chrony.tuxfamily.org/. 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.

This recommendation only applies if chrony is in use on the system.

Run the following command and verify remote server is configured properly:

# grep "^server" /etc/chrony/chrony.conf 
server <remote-server>

Multiple servers may be configured.
Run the following command and verify OPTIONS includes -u chrony:

# grep ^OPTIONS /etc/sysconfig/chronyd 
OPTIONS="-u chrony"

Additional options may be present.

Add or edit server lines to /etc/chrony/chrony.conf as appropriate:

server <remote-server>

Add or edit the OPTIONS in /etc/sysconfig/chronyd to include -u chrony:

OPTIONS="-u chrony"
