Traveller alert: DST change

Well, it won't really affect us much here as Thailand doesn't have DST. But if you are travelling during March beware, it appears that DST will change on March 11 htis 2007, about three weeks earlier than usual.

Date change in 2007

And on a similar subject:

British Summer Time Rule

From the last Sunday in March until the last Sunday in October the UK moves its clocks forward from Greenwich Mean Time by one hour (GMT+1). This is known as British Summer Time or BST for short.

(Therefore, the UK is six hours behind Thailand in summer, as opposed to seven hours in winter).

The word from Microsoft

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).

Those with computers running genuine XP will get the change automatically downloaded if so set up

I remember in the 70's that the U.S. DST changes were NOT well received. But, for this 3 week change, I think George will get this one to credit.

During the "energy crisis" years, Congress enacted earlier starting dates for daylight time. In 1974, daylight time began on 6 January and in 1975 it began on 23 February. After those two years the starting date reverted back to the last Sunday in April. In 1986, a law was passed permanently shifting the starting date of daylight time to the first Sunday in April, beginning in 1987. The ending date of daylight time has not been subject to such changes, and has remained the last Sunday in October. With the Energy Policy Act of 2005, the starting and ending dates have once again been shifted. Beginning in 2007, daylight time will start on the second Sunday in March and end on the first Sunday in November.
