There is some controversy over how much energy will (or won't) be saved:

... Fred Upton, a Republican congressman from Michigan who pushed the change. "For every single day that we extend daylight-saving time, we would save the energy equivalent of 100,000 barrels of oil." ...

But in a study last year, the U.S. Department of Energy estimated that, overall, this year's extension into March and November will probably save very little energy — far less than 1 percent of the nation's annual energy consumption.

Another recent study, by the California Energy Commission, came to a similar conclusion of a very small effect. ...

It mostly seems to have rolled over fine. All the computers I use at work seem ok, and most of my appointments seem ok in Outlook, with a couple of exceptions. For some reason, St. Patrick's Day, which is a holiday inserted by Outlook, became a two day holiday (Saturday and Sunday) - I guess the folks at MS are planning big hangovers. And another all day appointment I had became 1:00 to 1:30 a.m.

Seems likely to foster confusion.
And that is an additional beef that I have with that. They use the public's fear of oil instability to sell this energy thing. So, using your numbers, we actually saved 200 barrels of oil a day, and reduced coal or natural gas, and even saved on some renewables. Not as big of an impact.

But; the entertainment industry likes it.

Something that I was asking when they were spouting numbers. In fact, nobody knows.
This article quotes 10k bbl, Jim's article says 100k. The number is based on savings in a time when everybody cut back thier usage because of shortages and costs.

Then; on top of it, the article I posted blames the driving for the price increase, when 2 days before the time change I kept hearing "the price is up in California, how long before the same thing happens to the rest of the country".
Did it go up in California because the Californians all said "hey; I better fill up because I will do an extra hour of driving this weekend."?

There might be some truth or benefit buried in all this, but there's too many unsubstantiated claims.

(emphasis added)

That's a pretty meaningless statistic.

Should anyone be surprised that the proposed savings are less than 1% of the total? If you just shut everything off for an average hour, your savings would be ~4%.

100,000 barrels of oil is only about 0.5% of our daily petroleum consumption (actual, not energy equivalent) http://www.eia.doe.gov/neic/quickfacts/quickoil.html

That's a radio signal, though, not NTP. It ties into a different system.

For those that asked, my home computer is on XP, SP2, and I've downloaded all the recommended updates. I'm just going to leave it on standard time for three weeks and let it fix itself then. We don't really use the time for anything there.

Somewhat off-topic, I've got an old VCR I had to reset a few weeks ago and discovered it couldn't handle the year 2007! I had to tell it it was 2001.

AFAIK, the only issue at USNO that requires attention on DST changeover is the system that runs the voice announcer.
I'm going to look up the NTP protocol to see the details when I get a chance, but I had a DST problem with a particular NTP server. I would sync and it would kick it back (or foward) one hour -- I forget if was the DST or standard time transition. The local system was set correctly and had already noted the change. Contacting the NTP server tried to change it by one hour again.

I then switched to the USNO servers and the problem went away. So that tells me that the server itself can have some role in the DST setting, undoing what the local DST switchover logic is doing.

I'm thinking there has to be something else, because not everyone switches over to their version of DST at the same time, or at all. NTP just provides UTC to the computer, which then modifies it based on time zone and DST settings.

It knew you were supposed to replace it with a DVD recorder by now. Since you didn't, it's just sulking.

Watch out for when it's done with its sulk and starts spitting iron oxide at you.

It's quite happy now, living in March 2001. When you think about it, the world was a happier place back then.

I also discovered the "Automatically adjust clock for Daylight Saving Time" box on my computer was unchecked. Checked it, time adjusted. It has always done it automatically before, perhaps the SP2 update caused it to get unchecked.

I would just be happy about the more daylight in the evening.

My computer just now "up-dated" itself by adding an hour to its time display.

My dad's VCRs updated this weekend, as expected, but our radio clock (which supposedly is synchronized by broadcasts of WWV) also updated this weekend rather than in March. This clock has no means of entering a date, so why didn't WWV update until now?

Radio clock signals include date information but they are in UTC, it's your clock that has a DST rule and changed timezones.

Oops I was wrong.
I just read the data format for WWVB, it definitely says the DST information is included in the signal, it also says that it used the new rule for the data.

New guess, your clock uses a built in DST rule instead of using the info sent by WWVB, possibly to make it possible to turn it off for sales to Arizona.

WWVB Radio Controlled Clocks: Recommended Practices for Manufacturers and Consumers does allow for a built in rule, but recommends using the transmited info.

The very fancy VOIP phones my company is converting to didn't update two weeks ago -- a little surfing on the company web revealed that Cisco apparently doesn't have a fix! They did have a method for manually rebooting the phone so it would go get the time off the web. I did that and it worked. I'm not working today but may go in anyway just to see if the phone is (as I suspect) now an hour ahead!

But this computer is just fine and the old VCR still thinks it's 2001!

I think the military went over to Daylight Savings Time in Iraq this weekend, based on some things Graham said, but I'm not 100% sure.
