Daylight Savings Update Info

Beginning in 2007, most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November. In the U.S., each time zone switches at a different time. This is different than in years past which will require most systems and applications to have updates or patches to accommodate these changes.
