Exactly right. Both the Virginia and the Canada numbers are *always* on Eastern Standard Time, so CDT is +/- 0 hours time difference. One nice feature about the program, though, is that if you adjust the time difference setting, say from -1 hour to 0 hours, your clock is adjusted automatically without another call to the master clock. (If you just change your clock by an hour from the Control Panel, you lose a few seconds during the time you have the time selected.) For any interested Macintosh users, I think the file is available as some variation on "Set Clock" in the info-mac archives by ftp from sumex-aim.stanford.edu. The program just outdials at 300 bps on your modem to the master clock in VA or Ont. and receives a series of ASCII data lines along the lines of 023440 023441 023442 023443 900406 Your clock is then reset and you are told how much fast/slow it was.

Do they run a receiver on WWV and automatically adjust I am told that is what they do by my Pac*Bell friends. On the other hand, there is GTE who allowed their Los Gatos time signal to get several minutes off before a disgruntled subscriber finally called in to complain! Oh, well, I'm sure GTE would normally be happy if their time signal indicated the correct century. John Higdon | P. O. Box 7648 | +1 408 723 1395 john@bovine.ati.com | San Jose, CA 95150 | M o o !
