# 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. | |

# Set runtime command key. Note that if you change the key (not the | |

# /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 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. | |

# 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. | |
