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.

Solution

Add or edit server lines to /etc/chrony/chrony.conf as appropriate: server <remote-server> Configure chrony to run as the chrony user by configuring the appropriate startup script for your distribution. Startup scripts are typically stored in /etc/init.d or /etc/systemd.
