On Tuesday afternoon, just two days after Americans set their clocks forward an hour for Daylight Saving Time, the U.S. Senate passed a bill that would make Daylight Saving Time permanent, so that Americans wouldn’t have to turn their clocks back an hour. The overall effect of such a change would be that, in the winter when days are shorter, the extra darkness would shift toward the morning; rather than the sun setting in the middle of the afternoon in some places, it would rise later in the day.
