Yes, it's that time again: those glorious Daylight Saving Time days are over, as of 2AM on Sunday, Nov. 4. Seem later than last year? It is: Daylight Saving Time in 2007 started several weeks earlier, and ended a week or so later, than in recent years. The U.S. Congress claims that the change will save energy across the country—or is it just a sinister conspiracy to sell more Halloween candy? Either way, don't forget to set your clocks back one hour before bedtime, Saturday night. Want a little more history about Daylight Saving Time?
