clock not keeping time

I have found that when the pc fails to keep correct internal time,
this is an symptom of the motherboard battery going bad. Power off
PC, open case, find, and replace battery. It's looks like an thick
dime. After replacing, set time manually with date command and it
should be fine.

In general, use ntpd(8) to synch your sytem clock to various time
servers on the net. This works well on a broadband or always-on
connection, but be warned that it will bring up a dial-up line about
every twenty minutes, so it's probably not what you want in that
situation -- an alternative in that case is to use ntpdate(8) out of
your /etc/ppp/ppp.linkup script.
Here's a sample /etc/ntp.conf that you can probably just drop into
your system. See http://fortytwo.ch/time/ for details of the
'pool.ntp.org' system. Replace the nework number and netmask in the
3rd line with the ones appropriate to your site:
restrict default nomodify nopeer # Restrict access ...
restrict 127.0.0.1 # ... except for me ...
restrict 192.168.0.0 mask 255.255.255.0 # ... an the local net
See also the lists of public stratum 2 servers at
http://www.eecis.udel.edu/~mills/ntp/clock2a.html for some more
servers if you need them. Plus consult your ISP -- most will make
servers available for their customers.
To turn on NTP using the ntp.conf above in your system add:
ntpdate_flags="-b -s pool.ntp.org"
to your /etc/rc.conf (The 'xntpd' bit is historic -- ntpd(8) was
called xntpd(8) for some time).
