That won't work in my application. I can't run anything on any server but
one I provide specifically for time, which is why I'm looking at dedicated
time servers. Believe me when I say this crossed my mind and was crossed
off the list. Just about every system is MS Windows based which means

I had suggested the same thing. In fact I'd argue not having an NTP box is
more reliable than having one. A non-esistant box can't fail.
But don't run just one NTP server, run one on every non-overloaded
server. You clients will automatically sync with whichever server
is "best"

That's exactly what we've done in the past (setting it when on the network
and letting the clock do what it wants) and that's fine. The actual time
isn't as important as the agreement on what time it is. This is certainly
the cheaper way to go and is becoming a viable option.

esn't sound like this is a requirement for your application.

FWIW, you can't go wrong with Meinberg.
Several versions to choose from, reliable, and priced well.

I assume you don't have internet access. If you had access only a few
times per day you can get better than 1 second using remote servers

If you are rolling your own I would advise a Soekris net4501 (US $173 new) over
any netbook for several reasons: cheaper, more rugged, better solution overall.
It all comes down to requirements, budget, and who the user is (which drives
the first two). If I were doing a system for myself, it's h
What do you need to do? What precision is required and how many clients will
you be serving. For most "normal" uses you don't need a special purpose
server system. A $600 notebook PC and any GPS unit with a serial
connection and a copy of Linux or BSD.

Hi guys,
I'm looking to buy an NTP server for a field deployable server system. I
currently have a Symmetricom SyncServer S250 which does more than I need. I
am considering buying an S200 (same as the S250 but without the ability to
connect to an external frequency standard). My gut feeling is
