OK, but how? I've looked at all the docs I can find.
Does "ntpd -g" go in rc.conf?
Does it take the place of:
ntpdate_flags="-bs server1.domain1.com server2.domain2.com
Or, does the '-g' get added into:
xntpd_flags="-A -c /etc/ntp.conf -p /var/run/ntpd.pid -l
xntpd_flags="-A -g -c /etc/ntp.conf -p /var/run/ntpd.pid -l
Obviously, I'd like to set the clock with brute force
on boot up just in case it's off by quite a bit. Then
I would like it to quickly come into synch with the
time servers that I am polling, and finally maintain
accurate time on a continual basis.
I would certainly like to keep up to standards, but
ntpdate on boot up seems to be working OK. What is
the proper way to replace it and maintain my other

Great! Will do. Has been taking quite a while
to synch up. How long does it usually take
to synch up using iburst? My broadcast signals
don't go out until the server is synched.

I recompiled the older version with the broadcastclient fix. The
'sendto Permission denied' error went away.

I am writing a 'How To' on how to install NTP on FreeBSD. It will
be primarily a step-by-step guide, aimed at intermediate users,
who want to get a server up and running quickly.
A link to it will be at the bottom of:
