Laura, is the cheap WWVB clock that botches changes sometimes,
a Radio Shack Atomic Clock 630-0979? I have one that sometimes
missed the time change as it did this time till I told it to
"re-sync". My WWVB wall clocks never miss.
-Sam

It says it's SkyScan model 31981B.

It's probably 99% the same clock, though I bought it at Fry's
Electronics instead of Radio Shack.

There's very little inside it apart from a ferrite antenna, the LCD
and a big honker of an ASIC.

Unfortunately not my 2610.

Us people that keep using older products because they work better don't
get much respect do we? I had my 2610 on Auto but when I switched it
Daylight it was back on the money. I suppose I'll have to undo that in
the fall. Oh the agony of it all...

Does this imply there will be lots of firmware updates from Garmin to
address this silly daylight time change?

I'd say wait and see if the two year experiment stays in place or
reverts back to the old formula.

What? This is only a 2 year experiment? Personally I think 2 year is
too short, just when people get around to replace their electronics,
it reverts back...

The clock is tries to receive WWV broadcasts in the early hours of the
morning, local time, because that is when propogation is best.
My $5 Sharp clock won't sync WWV during the day, but it never seems to fail
at night. My LaCrosse weather station is the same way, can't sync during
the day, works at night. They both changed to DST on Sunday. The Lacrosse
has an option to ignore DST.

That's actually WWVB, down on 60 kHz, and the NIST
have an interesting web page about it. Unless you
live in the vicinity of Colorado, you're not going to
receive WWVB during the day.

<http://tf.nist.gov/timefreq/stations/wwvb.htm>

The HF WWV signals have lots of interesting information,
but aren't as useful for setting clocks. CHU broadcasts
a time code on HF - the warbly-sounding "ticks". On
a recent trip to Central America I could hear somebody
else's time signal station on 5 MHz underneath WWV,
but never IDed it.

I still have my recording of latest leap second on WWV.
Lame or what? :-)

Ooh, Ooh, Ooh! Are you a contributor towww.globalslowing.org?

No, but I *do* get emails from the Earth Rotation Service! <http://
www.iers.org>

For those who are curious, the last leap second on WWV sounded
something like this:

tick (23:59:56 UTC)
tick (23:59:57 UTC)
tick (23:59:58 UTC)
(silent) (23:59:59 UTC)
(silent) (23:59:60 UTC)
BEEP (00:00:00 UTC)

Normally there is only the one silent tick at 59 seconds.

The story I've heard about leap seconds is that for a long
time the consortium that defined UTC had one organization,
supposedly in Mongolia, that kept really crummy time (by
atomic clock standards). The large residuals from comparing
this clock to the others made it look like Earth's rotation was
slowing down more rapidly than it really was, hence lots of
leap seconds. Now they ignore the Mongolians and their
crummy clock, and we won't have any more leap seconds
for some time to come.

Not true, I get it most days at mid day in Rochester, MN.

I suspected YVTO as well.

From home I often hear stuff from across the Pacific.
VNG used to be a handy propagatin beacon, and one

morning I had WWV, WWVH, VNG and BPM all on
top of each other on 5 MHz.

Ironically, CHU can be tough from here...
