    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

        server pool.ntp.org
        server pool.ntp.org
        server pool.ntp.org

        pidfile /var/run/ntpd.pid
        driftfile /var/ntp/ntp.drift

    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
    NTP
    servers available for their customers.

    To turn on NTP using the ntp.conf above in your system add:

        ntpdate_enable="YES"
        ntpdate_flags="-b -s pool.ntp.org"
        xntpd_enable="YES"
        xntpd_flags=""

    to your /etc/rc.conf (The 'xntpd' bit is historic -- ntpd(8) was
    called xntpd(8) for some time).

            Cheers,

            Matthew
