Um, the time change takes place at 2 AM in the USA, springing ahead to 3 AM or falling back to 1 AM. This avoids repeating the date in the fall.
Surely, other cultures don't do it differently, do they? ;-) Bill Hawkins It's widely true that the time of minimum human activity is 4:30 AM. Why not do it then? -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Brooke Clarke Sent: Monday, November 02, 2009 9:50 AM To: Discussion of precise time and frequency measurement Subject: Re: [time-nuts] WWV Clock Hi Mike: Note that the way a clock checks to see of it has received the data correctly is to compare two adjacent frames and check to see that they differ by one minute. If the clock was smart it would start to listen a few minutes prior to midnight and would recognize that there was going to be a DST change at midnight. If the clock started at what it thought was midnight, but it was running a second slow then it would miss the first frame, but the next minute it would get the "new" frame and switch to/from DST. I think your clock is just not receiving a good enough signal. The key may be you need to mount the clock on a wall that's 90 degrees from where it is now. That's the problem I had with an atomic clock, i.e. the loopstick antenna has deep nulls and if you point the null at the transmitter . . .
