Set your clocks back it’s Standard time again…

Set your clocks back makers it’s Standard time again

Starting in 2007, daylight time begins in the United States on the second Sunday in March and ends on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour at 2:00 a.m. local standard time, which becomes 3:00 a.m. local daylight time. On the first Sunday in November, clocks are set back one hour at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time. These dates were established by Congress in the Energy Policy Act of 2005, Pub. L. no. 109-58, 119 Stat 594 (2005).

Although standard time in time zones was instituted in the U.S. and Canada by the railroads in 1883, it was not established in U.S. law until the Act of March 19, 1918, sometimes called the Standard Time Act. The act also established daylight saving time, a contentious idea then. Daylight saving time was repealed in 1919, but standard time in time zones remained in law. Daylight time became a local matter. It was re-established nationally early in World War II, and was continuously observed from 9 February 1942 to 30 September 1945. After the war its use varied among states and localities. The Uniform Time Act of 1966 provided standardization in the dates of beginning and end of daylight time in the U.S. but allowed for local exemptions from its observance. The act provided that daylight time begin on the last Sunday in April and end on the last Sunday in October, with the changeover to occur at 2 a.m. local time.

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 that shifted the starting date of daylight time to the first Sunday in April, beginning in 1987. The ending date of daylight time was not subject to such changes, and remained the last Sunday in October. The Energy Policy Act of 2005 changed both the starting and ending dates. Beginning in 2007, daylight time starts on the second Sunday in March and ends on the first Sunday in November.

    It leads to nothing but misery and death with no equivalent benefit.

    Actually it’s not daylight time anymore, it’s back to standard time.

    Yesterday I got a clock at The Great Evil… I mean Wal-Mart, that sets itself, and automatically adjusts for DST. No more trouble with having to remember to move forward or back, so I’m pretty indifferent to it.

    On the other hand, weren’t there some studies that indicated that the Energy Policy Act of 2005 and the associated DST shift actually used MORE energy than the previous DST setup, thereby making itself an epic failure?

    Yeah, I have one of those. I got it about 4-5 years ago. It worked great. THEN THEY WENT AND CHANGED THE DST RULES AND NOW IT CHANGES ON THE WRONG DATE. Now it’s less useful than one that doesn’t change automatically because I have to remember the old time change dates so I can fix it.

    But I’m not bitter. Not at all.
