This morning we overslept. But it wasn't our fault; it was the fault of our clock-radio trying to be smart. It's one of those clocks that has some internal firmware that automatically changes the time by one hour on the beginning and ending days of DST. But it was only half-smart, because it didn't know about the U.S. Energy Policy Act of 2005, which postponed the end of DST until next weekend this year. I guess that's what people mean when they say, "A little knowledge is a dangerous thing."
