Starting in the spring of 2007, daylight saving time (DST) start and end dates for the United States will transition to comply with the Energy Policy Act of 2005. DST dates in the United States will start three weeks earlier (2:00 A.M. on the second Sunday in March) and will end one week later (2:00 A.M. on the first Sunday in November).

From http://java.sun.com/developer/technicalArticles/Intl/USDST/:

"Problems Affecting Java Applications"

"The Java Runtime Environment (JRE) stores rules about DST observance all around the globe. Older JREs will have outdated rules that will be superseded by the Energy Policy Act of 2005. As a result, applications running on an older JRE may report incorrect time from March 11, 2007 through April 2, 2007 and from October 29, 2007 through November 4, 2007."


From http://www.microsoft.com/windows/timezone/dst2007.mspx:

"Supporting the DST changes on Windows operating systems"

"For Windows XP Service Pack 2 (SP2), Windows Server 2003, and Windows Server 2003 Service Pack 1 (SP1), Microsoft will release a single global time zone update which will include changes for the United States DST change. This time zone update will also include changes for other related DST changes and time zone behavior and settings that will take place in 2007 or have taken place since these versions of Windows were originally released. It will include some changes that have previously been released as individual hotfixes (such as the Sri Lanka change in time zone offset) or have been individually documented in prior Knowledge Base articles. These updated time zone definitions will also ship with Windows Vista."

"Windows Vista will have these changes included in the release-to-market version of the operating system. Windows XP SP2 and Windows Server 2003 will require the update. Windows XP SP1 and older operating system versions have passed their end of support dates and will not be receiving the update. Windows 2000 has passed the end of mainstream support and will not be receiving an update without an Extended Support Hotfix Agreement. Find more information about support policies around hotfixes."

"Versions of Windows which are not currently supported can be manually updated using the tzedit.exe utility or other techniques documented in Knowledge Base article 914387 and similar articles for other countries. Find more information about support policies around hotfixes."

No, daylight saving was first implemented in europe during one of their various periodic bloodletting purges to kill off the middle class. Efficient use of factories and labor, as they utilized large expanse of windows to let natural light in for illumination. Why they just couldn't get everyone up earlier is a mystery to me, but instead they decided to fiddle with the clocks. Anyway, the US followed suit for WWI as well, and then WWII, and eventually, it became pretty much, uh, standard across the US, with a few oddball exceptions and Hawaii.
