I am looking for a good www. to set and maintain my clock so I can get the most accurate time for my telescope. I see lots of internet sites, any suggestions? Thanks, Ted

I like Atom Time. It's a little program that will help keep your PC clock in sync with the atomic clock in Boulder, CO.

They also sell regular clocks these days that basically do the same thing. They listen to a special radio frequency that carries the official US time and will keep in sync.

Here is one (http://nist.time.gov/)that is web based but will not sink or maintain your computer but it is free.

What about time as indicated on a handheld GPS unit? I recall reading somewhere that GPS satellites transmit a time synch signal every 7(?) minutes or so. such that a GPS left on for around ten minutes would have updated its own clock to the GPS standard. On a few occasions when I have compared GPS time to a clock recently updated by one of the methods described previously the results were pretty good. It bothers me, however, that the time indicated on my two identical GPS receivers (Magellan 330) seemingly always disagrees by a couple of seconds. GPS experts?
