Today is the start of Daylight Saving Time. Clocks jumped forward an hour at 2 a.m. Each year, Daylight Saving Time runs from the second Sunday in March to the first Sunday in November. As a result, the sun will be up an hour later each day. Instead of setting at 6:08 p.m. like it did Saturday, it will set at 7:17 p.m. this evening.
