Sorry if everybody else already knew about this but this is the first I've heard about it. The changes in daylight savings time start this year. Here's the relevant section of the Wikipedia article:

The bill amends the Uniform Time Act of 1966 by changing the start and end dates of daylight saving time starting in 2007. Clocks will be set ahead one hour on the second Sunday of March instead of the current first Sunday of April. Clocks will be set back one hour on the first Sunday in November, rather than the last Sunday of October. This will make electronic clocks that had pre-programmed dates for adjusting to daylight saving time obsolete and will require updates to computer operating systems. The date for the end of daylight saving time has the effect of increasing evening light on Halloween (October 31).

I guess this is probably good from an energy savings perspective, but I'm kind of surprised I didn't hear about it before now.
