# Welcome to the chrony configuration file. See chrony.conf(5) for more
# information about usuable directives.
# This will use (up to):
# - 4 sources from ntp.ubuntu.com which some are ipv6 enabled
# - 2 sources from 2.ubuntu.pool.ntp.org which is ipv6 enabled as well
# - 1 source from [01].ubuntu.pool.ntp.org each (ipv4 only atm)
# This means by default, up to 6 dual-stack and up to 2 additional IPv4-only
# sources will be used.
# At the same time it retains some protection against one of the entries being
# down (compare to just using one of the lines). See (LP: #1754358) for the
# discussion.
#
# About using servers from the NTP Pool Project in general see (LP: #104525).
# Approved by Ubuntu Technical Board on 2011-02-08.
# See http://www.pool.ntp.org/join.html for more information.

# This directive specify the location of the file containing ID/key pairs for

keyfile /etc/chrony/chrony.keys
# 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, /etc/init.d/chrony
# and /etc/cron.weekly/chrony as these scripts use it to get the password.

# This directive specify the file into which chronyd will store the rate
# information.

# Uncomment the following line to turn logging on.

# Log files location.

# Stop bad estimates upsetting machine clock.
maxupdateskew 100.0
# This directive enables kernel synchronisation (every 11 minutes) of the
# real-time clock. Note that it cant be used along with the 'rtcfile' directive.

# Dump measurements when daemon exits.

# Specify directory for dumping measurements.

# This directive forces `chronyd' to send a message to syslog if it
# makes a system clock adjustment larger than a threshold value in seconds.
logchange 0.5
# 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.
# mailonchange root@localhost 0.5
# 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. I've commented it out because with certain
# combinations of motherboard and kernel it is reported to cause lockups.
# rtcfile /var/lib/chrony/chrony.rtc
# 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.
