title: 'Chrony Configure Pool and Server'
description: |-
<tt>Chrony</tt> is a daemon which implements the Network Time Protocol (NTP). It is designed to
synchronize system clocks across a variety of systems and use a source that is highly
accurate. More information on <tt>chrony</tt> can be found at
{{{ weblink(link="https://chrony-project.org/") }}}.
<tt>Chrony</tt> can be configured to be a client and/or a server.
Add or edit server or pool lines to <tt>{{{ chrony_conf_path }}}</tt> as appropriate:
<pre>server <remote-server></pre>
Multiple servers may be configured.

If <tt>chrony</tt> is in use on the system proper configuration is vital to ensuring time
synchronization is working properly.
