+# This the default chrony.conf file for the Debian chrony package.  After

+# 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.
