# 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.

# and /etc/cron.weekly/chrony as these scripts use it to get the password.
