This information is about daylight saving time this year. It consists of various information I have put together from various sources.
This will effect our computers and various other electronic equipment using automatic daylight saving time adjustments.
Beginning in 2007, most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time.
In the European Union, Summer Time begins and ends at 1:00 a.m. Universal Time (Greenwich Mean Time). It begins the last Sunday in March and ends the last Sunday in October. In the EU, all time zones change at the same moment.
In past years the time change was the last Sunday in March and ends the last Sunday in October. This year 2007 there is about a 2 week difference. Clocks will spring forward Sunday March 11, 2007.
Below is a chart showing dates of past years and future years.

Microsoft Issues Warning On Daylight-Saving Time Software Flaw
Microsoft says the Y2K-like implications of the change in the start of daylight-saving time means computer users need to parry like it's 1999.

Microsoft is warning customers that the switch to early daylight-saving time this year isn't accounted for in a number of its products, including Windows XP, and that users will need to update their software to avoid potential problems.
U.S. daylight-saving time will start on March 11 this year -- three weeks earlier than usual. The change was authorized by the U.S. Energy Policy Act of 2005, but Microsoft says its Y2K-like implications mean computer users need to parry like it's 1999.
"Unless certain updates are applied to your computer, it is possible that the time zone settings for your computer's system clock may be incorrect during this four-week period," the software maker said in a statement issued Tuesday.
That could lead to all kinds of problems, from calendaring applications not working properly to key, automated processes not taking place on time.
Microsoft said the fix is already built into Windows Vista and Office 2007, but that earlier operating systems and applications could be hit by the problem.
As of Tuesday, the company had released an update for Windows XP SP2 users via its Automatic Updates service. Users need to ensure they have Auto Update enabled.
Most of Microsoft's other major products, including Outlook 2007 and its predecessors, Windows NT, Windows 2000, Visual Studio, Windows CE, and a number of others, need to be updated, meaning some long nights may be in store for IT staffers leading up to the time switch.
Microsoft also warned that the problem isn't limited to its software. Consumer appliances such as VCRs and digital radios may not automatically adjust to the early start of daylight-saving time. Many systems on the business technology side also could be affected. IBM, for instance, has issued updates for some of its disk storage products and other systems.
This will effect our computers and various other electronic equipment using automatic daylight saving time adjustments.
