Hi Ted,
You can get details of time servers from =
http://tf.nist.gov/timefreq/index.html
A good free server is AboutTime See =
http://www.arachnoid.com/abouttime/=20
It sends you the correct time, your computer then 'pings' =
AboutTime, which returns the signal immediatly, allowing your computer =
to measure and correct for time delays on the line.
It is possible to buy a WWVB time receiver which automatically =
corrects your computer or network.=20
Another alternative is to buy one of the Radio Corrected WWVB =
wall clocks with a sweep second hand. You can fit a LED and a photocell =
on the dial and sense the second hand for the minute marks. Bob does =
this Bobhelenmcclure@....... - you need a large second hand to do this, =
or an Al foil extension. I am not sure what software he uses.
=20
I seem to remember that you can also buy the radio PCB and a =
computer board to decode WWVB signals from Galleon at =
http://www.ntp-time-server.com/ These are produced in Germany for all =
radio time systems. I use a similar system on DCF77 in Europe.

Chris Chapman
