Hate to burst your bubble Fieldmouse but I don't think the change will take effect until next Fall. I think that is what was originally called for but that the government reduced the amount of time it would be extended dramatically. Here's what I found, though this may be outdated. I would have loved the extra time after work!

"On August 8, 2005, President George W. Bush signed the Energy Policy Act of 2005. This Act changed the time change dates for Daylight Saving Time in the U.S. Beginning in 2007, DST will begin on the second Sunday of March and end the first Sunday of November. The Secretary of Energy will report the impact of this change to Congress. Congress retains the right to revert the Daylight Saving Time back to the 2005 time schedule once the Department of Energy study is complete."
