# This the default chrony.conf file for the Debian chrony package.  It is
# suitable for a system with an intermittent dial-up connection.  After
# editing this file use the command 'invoke-rc.d chrony restart' to make
# your changes take effect.

# 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 the link comes up and off when it goes
# down.  If you have an always-on connection such as cable omit the
# 'offline' directive and chronyd will default to online.

# Look here for the admin password needed for chronyc.  The initial
# password is generated by a random process at install time.  You may
# change it if you wish.

# Set runtime command key.  Note that if you change the key (not the
# password) to anything other than 1 you will need to edit
# /etc/ppp/ip-up.d/chrony, /etc/ppp/ip-down.d/chrony, and
# /etc/cron.weekly/chrony as these scripts use it to get the password.

# This directive forces `chronyd' to send a message to syslog if it
# makes a system clock adjustment larger than a threshold value in seconds.

# This directive defines an email address to which mail should be sent
# if chronyd applies a correction exceeding a particular threshold to the
# system clock.

# This directive tells chrony to regulate the real-time clock and tells it
# Where to store related data.  It may not work on some newer motherboards
# that use the HPET real-time clock.  It requires enhanced real-time
# support in the kernel.

# If the last line of this file reads 'rtconutc' chrony will assume that
# the CMOS clock is on UTC (GMT).  If it reads '# rtconutc' or is absent
# chrony will assume local time.  The line (if any) was written by the
# chrony postinst based on what it found in /etc/default/rcS.  You may
# change it if necessary.
