Maybe we should just remain on daylight saving time all the time. However, people in the western portion of their time zones would have to stomach sunrises at 9 a.m. and later around early January, especially toward the north. Way to the north, some people already enjoy 9 a.m. sunrises due to the combination of advanced clocks and length-of-day disparities.

Me too, but I wouldn't want to live there again.

strange: Emerson Research Auto update Clocks ARE NOT UPDATING off Satellite

all three clocks @ our House aren't able to be changed to the Correct TIme arghhh!!!

anybody 'ave any of these clocks?

strange: Emerson Research Auto update Clocks ARE NOT UPDATING off Satellite

Most likely your clocks use use radio (WWVB) not satellites as their time source.

These designs usually only update one or a very few times per day. Most likely your clocks have not had a successful reception since the time change (which was at 2:00 a.m.). Probably they will get it tonight--assuming you have them in places where they can actually get the signal.

thanks archae86 . . . just as i saw your Post - i had unplugged the Radio = replugged it baCk in and found it had gone to Tome Zone 2 - i am in Zone 1 - so i set it for 1 and it updated correctly just now . . . again Thanks . . .

Here in Edmonton, Alberta, (at 53.6° N, and 34 minutes west of our standard time meridian) sunrise was at right around 8:00 this morning, and many people will be going to work in the dark or twilight tomorrow. It’s only ten days to the spring equinox: obviously sunrise comes later in early January! Were we to switch to year-round DST our latest would come at about 9:50 AM.

This time of the year, when the equinox occurs in only nine days, northern exposure effects are minimal. But it's another story near the solstices. When up north one has to stomach irregular sunrises/sets, and long dawns and twilights. The only solution is to move south. If a person moved to Quito, Ecuador (actually a few kilometers north of that) and left his/her clocks alone the only effect of change of sunrise/transit/set would be shown on the analemma (equation of time) of about +-16 minutes throughout the year due to the eccentricity of Earth's orbit.

Also due to the obliquity of the ecliptic: the equation of time is a compound effect.

Of course for such a massive object(Relatively at least), It's amazing that the earth at the equator spins at 10,000Mph or so.

Closer to 1,000 Mph. The Earth is about 25,000 miles round, and last time I looked, it covered that distance in about 24 hours ;-).

However, relative to the sun, those in darkness get an extra speed boost compared to those lazing in the sunshine...

But, by how much?

The back of my envelope says 2 pi r - 93 million miles - 365*24 hours -

- orbital speed of 66,700 Mph (rough average, it's an ellipse, of course).

- and y'all thought we were living in a nice, quiet, 'rock solid' sort of place...

Putting Richard’s approximations together, 66700 ±1000 mph is a variation of ±1.5%, so WRT the Sun someone on the Equator would move about 3% faster at midnight than at noon.

I make the Earth’s orbital speed about 30 km/s, and the rotation about 0.46 km/s, to the same effect. At my latitude (likely similar to yours) the latter figure is more like 0.28 km/s, for a noon-to-midnight “boost” of less than 2%.

For another back-of-the-envelope comparison, consider that the solar system is orbiting the Galaxy at something like 280 km/s, making the annual range in the Earth’s speed only about 10% of the mean.

I like the way Arizona does it.. no DST at all.

The reservations in AZ do observe DST. I also think Hawaii does not do DST. There is a few cities in IN that also do not observe DST.

Not any more...we all had to pick (via our elected offarcicals) whether we wanted CST or EST - and then they threw in DST just to be cute.

Official Equation: EST + DST - CST = BST (Bull S*it Timezone)

Not true anymore. Indiana went to DST as of last year. Personally, as one who went from no DST to now using DST, I hate DST.

Opps. I didn't read all of the thread before I posted. I see that someone else said basically the same thing I did.

Why do you hate it? I hate when we have to move our clocks back one hour in the Fall. I love being on DST. We get more sunshine well into the evening that way.

Let's just make the whole world fit us night owls' schedule! Advance every time zone by, say, three hours! That way, it'll still be light until almost midnight!

I think I have a 27hour circadian rhythm. If the world changed to a 27hour day I would probably sleep better and we certainly wouldn't have to bother with DST.
