4 # Default NTP servers for the FreeBSD operating system.

9 # The driftfile is by default /var/db/ntpd.drift, check
10 # /etc/defaults/rc.conf on how to change the location.
14 # The following three servers will give you a random set of three
15 # NTP servers geographically close to you.
16 # See http://www.pool.ntp.org/ for details. Note, the pool encourages
17 # users with a static IP and good upstream NTP servers to add a server
18 # to the pool. See http://www.pool.ntp.org/join.html if you are interested.
20 # The option `iburst' is used for faster initial synchronisation.
21 # The option `maxpoll 9' is used to prevent PLL/FLL flipping on FreeBSD.

43 # Please note that this example doesn't work for the servers in
44 # the pool.ntp.org domain since they return multiple A records.

56 # If a server loses sync with all upstream servers, NTP clients
57 # no longer follow that server. The local clock can be configured
58 # to provide a time source when this happens, but it should usually
