You should configure at least three (3) time sources for the best, most accurate timekeeping. The NTP "pool" is a wonderful source sink:

Re: configuring NTP
If you are new to NTP configuration as the pharoah said, it's the simplified list. However, some typo errors:-
edit /etc/ntp.conf
edit /etc/rc.config.d/netdaemons
:)

Re: configuring NTP
The best thing you can do is go get a coffee. By the time you come back, it will likely be working.
Sometimes it's worthwhile to restrict the client / server config..
restrict default ignore
restrict 192.168.1.81 mask 255.255.255.255 nomodify notrap noquery
restrict 192.168.1.84 mask 255.255.255.255 nomodify notrap noquery
This would definitely limit any NTP allowed responses to the ntp servers 192.168.1.81 and .84.
For servers, go the other way and limit connections to only your hosts:
restrict 192.168.1.0 mask 255.255.255.0 nomodify notrap
Also, using the NTP pools is a great idea, as it localises your NTP sources, and also doesn't overload the tier 1 sources, but it has the limitation of not working through a firewall unless you are willing to open udp/123 to your clients/NTP server. Better to have a couple of internal sources that you trust and have them go out to a tier 2 or tier 1 source in a firewalled fashion (preferably from your DMZ.. then get the time from the hosts in your DMZ from internal). Routers also do this well...
Best regards,
Don
