7 # See www.pool.ntp.org for an explanation of these servers. Please
8 # consider joining the project if possible. If you can't or don't want to
9 # use these servers I suggest that you try your ISP's nameservers. We mark
10 # the servers 'offline' so that chronyd won't try to connect when the link
11 # is down. Scripts in /etc/ppp/ip-up.d and /etc/ppp/ip-down.d use chronyc
12 # commands to switch it on when the link comes up and off when it goes
13 # down. If you have an always-on connection such as cable omit the
14 # 'offline' directive and chronyd will default to online.
19 # Look here for the admin password needed for chronyc. The initial
20 # password is generated by a random process at install time. You may
21 # change it if you wish.
23 keyfile /etc/chrony/chrony.keys
25 # Set runtime command key. Note that if you change the key (not the
26 # password) to anything other than 1 you will need to edit
27 # /etc/ppp/ip-up.d/chrony, /etc/ppp/ip-down.d/chrony, and
28 # /etc/cron.weekly/chrony as these scripts use it to get the password.
32 # I moved the driftfile to /var/lib/chrony to comply with the Debian

64 # This directive forces `chronyd' to send a message to syslog if it
65 # makes a system clock adjustment larger than a threshold value in seconds.
69 # This directive defines an email address to which mail should be sent
70 # if chronyd applies a correction exceeding a particular threshold to the
73 # mailonchange root@localhost 0.5
75 # This directive tells chrony to regulate the real-time clock and tells it
76 # Where to store related data. It may not work on some newer motherboards
77 # that use the HPET real-time clock. It requires enhanced real-time
78 # support in the kernel.

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