Dear list readers -

Sorry to cause some additional noise on the list, but I am looking for
help in building a strat1 or 2 time server. I have a Fedora Core 6
server running with the latest NTP server installed. What I am trying
to
do actually is build an authoritative or reference time server that we
can use here for testing daylight saving time adjustments in our
environment. After thinking about it, I have come to the sane
conclusion
that this wont work with a normal ntp server as it will constantly
want
to FIX the time back and my ntpclients wont pull time if the server is
out of whack. So I need to build an ntp server that doesn't go out and
sync with an outside source, that my clients can use in this test
environment. So, my question is, just how do you build one?


The only way that I know of to get this kind of a time source, is to
actually have a strat1 or 2 time source in your location. We had this
discussion here at the office a while back, since we ahve a strat2
cesium clock to sync all our SONET rings. Even then, if you don't have
people actually syncing from the strat2 directly, and only have the ntp
server syncing it, it will still technically be only a strat3 time
source.

HTH.

Mark -

Yes that's helpful. So is there no way I can say have a windows box
connect to this server and pull its time successfully even though the
ntp server is an hour behind, or say we roll the date forward to March
11, 2007? You can see where we are going with this as far as testing is
concerned, they want to be absolutely sure they have thought of
everything - and asked me to build this. And that's when it hit me luck
a brick that this wont work well if its going out to a strat2 and
syncing, LOL.

Any additional thoughts?
Michael
