Like I say, I *have* fedora, I'm not planning to uninstall it as it was

Dave,
Fedora will be fine as a basic network time server. If NTP isn't already
installed on the system, all you have to do is type (as
root):
yum install ntp
The default config usually queries the NTP Pool. Depending on where you live
you might want to edit the file to use only your
country's

You might consider switching to FreeBSD for more reasons than just
timing, It's much faster than Fedora and I found the new 7.1 version easy
much faster in what respect? tested how?

I did dabble with Redhat Linux once before in the 1990s, and still have
the scars to show for it, so please

It's probably already running ntpd and setup to get time from a few pool

Start by doing:
ntpq -p
If that works, look in
RedHat in the 90s was terrible. It's much better now.
Last thing I read about ntp was that it was kind of broken for high
precision stuff on Linux and people tend to use FreeBSD. I duplicated the

Ouch. In some circles, those are fightin' words.
FreeBSD is _not_ Linux, in any way except being Unix-like.
