It is just past 11 pm on Saturday night here in Seattle. In three more hours, at 2 am, we will turn our clocks back one hour to make them Standard Time again (except the state of Arizona, since they don’t observe Daylight Savings Time). Watch out if you walk around after dark with traffic nearby! A Carnegie Mellon University study found that pedestrians are three times as likely to be hit and killed by cars in the few weeks after the time change back to Standard Time.
