"In 2009, daylight time begins on March 8 and ends on November 1."

 이번 주 주일인 3월 8일 오전 2시가 3시로 바뀝니다. 다시 말씀드리면 평소보다 한 시간 일찍 일어나셔야 합니다. 토요일 저녁에 주무시기 전에 시계를 바꿔 놓으세요. 예를들어 토요일 저녁 11시가 저녁 12시로 바뀌는 겁니다.

"Starting in 2007, daylight time begins in the United States on the second Sunday in March and ends on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour at 2:00 a.m. local standard time, which becomes 3:00 a.m. local daylight time. On the first Sunday in November, clocks are set back one hour at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time. These dates were established by Congress in the Energy Policy Act of 2005, Pub. L. no. 109-58, 119 Stat 594 (2005)."
