Prepare to buy new clocks

I have a handy alarm clock that automatically adjusts for daylight savings. Thanks to the US Congress, I get to replace it next year:

Starting in March 2007, daylight time in the United States will begin on the second Sunday in March and end on the first Sunday in November.

[ Daylight Time ]

How on earth could congress make a change to the US policy regarding Daylight Savings and not have it be to get rid of it? Now we're extending it by another month (give or take)?

And, for those of us that write software, we need to think hard if we coded for daylight savings anywhere, and update that code. Perhaps congress is worried that we don't have enough to program, and changing the rules frequently will help to employ programmers...
