# Default NTP servers for the FreeBSD operating system.
#
# Don't forget to enable ntpd in /etc/rc.conf with:
# ntpd_enable="YES"
#
# The driftfile is by default /var/db/ntpd.drift, check
# /etc/defaults/rc.conf on how to change the location.
#
#
# The following three servers will give you a random set of three
# NTP servers geographically close to you.
# See http://en.wikipedia.org/wiki/NTP_pool for details.
#
# The option `iburst' is used for faster initial synchronisation.
# The option `maxpoll 9' is used to prevent PLL/FLL flipping on FreeBSD.

# If you want to pick yourself which country's public NTP server
# you want sync against, comment out the above servers, uncomment
# the next ones and replace CC with the country's abbrevation.
# Make sure that the hostnames resolve to a proper IP address!
#
# server 0.CC.pool.ntp.org iburst maxpoll 9

# Security: Only accept NTP traffic from the following hosts.
# The following configuration example only accepts traffic from the
# above defined servers.
#
# Please note that this example doesn't work for the servers in
# the pool.ntp.org domain since they return multiple A records.
# (This is the reason that by default they are commented out)

# If we lose sync against all configured servers, the NTP clients
# syncing against this server will lose sync too. To overcome this,
# we will act as a stratum 10 server with our own internal clock
# so that everybody at least will have the same time as we have.
