NAME

       chrony.conf - chronyd configuration file

SYNOPSIS

       /etc/chrony/chrony.conf

DESCRIPTION

       chrony  is  a  pair  of programs for maintaining the accuracy of computer clocks. chronyd is a background
       daemon program that can be started at boot time.

       Assuming that you have found some servers, you need to set up a configuration file to  run  chrony.   The
       (compiled-in)  default location for this file is /etc/chrony/chrony.conf.  Assuming that your NTP servers
       are called `foo.example.net',  `bar.example.net'  and  `baz.example.net',  your  chrony.conf  file  could
       contain as a minimum

            server foo.example.net
            server bar.example.net
            server baz.example.net

       However,  you  will  probably  want  to  include  some of the other directives described in detail in the
       documentation supplied with the distribution (chrony.txt and chrony.texi). The following  directives  may
       be particularly useful : `driftfile',  `makestep', `rtcsync'.  Also, the `iburst' server option is useful
       to  speed  up  the  initial synchronization.  The smallest useful configuration file would look something
       like

            server foo.example.net iburst
            server bar.example.net iburst
            server baz.example.net iburst
            driftfile /var/lib/chrony/drift
            makestep 10 3
            rtcsync

       When using a pool of NTP servers (one name is used for multiple servers which may change over time), it's
       better to specify  them  with  the  `pool'  directive  instead  of  multiple  `server'  directives.   The
       configuration file could in this case look like

            pool pool.ntp.org iburst
            driftfile /var/lib/chrony/drift
            makestep 10 3
            rtcsync
