# Don't forget to enable ntpd in /etc/rc.conf with:
|
|
# ntpd_enable="YES"

# Set the target and limit for adding servers configured via pool statements
|
|
# or discovered dynamically via mechanisms such as broadcast and manycast.
|
|
# Ntpd automatically adds maxclock-1 servers from configured pools, and may
|
|
# add as many as maxclock*2 if necessary to ensure that at least minclock
|
|
# servers are providing good consistant time.

# The following pool statement will give you a random set of NTP servers
|
|
# geographically close to you. A single pool statement adds multiple
|
|
# servers from the pool, according to the tos minclock/maxclock targets.
|
|
# See http://www.pool.ntp.org/ for details. Note, pool.ntp.org encourages
|
|
# users with a static IP and good upstream NTP servers to add a server
|
|
# to the pool. See http://www.pool.ntp.org/join.html if you are interested.
