 +# This the default chrony.conf file for the Debian chrony package.  After
 +# editing this file use the command 'invoke-rc.d chrony restart' to make
 +# your changes take effect.  John Hasler <jhasler@debian.org> 1998-2008
  
 +# See www.pool.ntp.org for an explanation of these servers.  Please
 +# consider joining the project if possible.  If you can't or don't want to
 +# use these servers I suggest that you try your ISP's nameservers.  We mark
 +# the servers 'offline' so that chronyd won't try to connect when the link
 +# is down.  Scripts in /etc/ppp/ip-up.d and /etc/ppp/ip-down.d use chronyc
 +# commands to switch it on when a dialup link comes up and off when it goes
 +# down.  Code in /etc/init.d/chrony attempts to determine whether or not
 +# the link is up at boot time and set the online status accordingly.  If
 +# you have an always-on connection such as cable omit the 'offline'
 +# directive and chronyd will default to online.
 +#
 +# Note that if Chrony tries to go "online" and dns lookup of the servers
 +# fails they will be discarded.  Thus under some circumstances it is
 +# better to use IP numbers than host names.
