Congress has changed the dates for Daylight Saving Time (DST) in the United States starting in 2007. Canada has adopted similar DST dates.
These changes could cause clocks and Microsoft Outlook calendar appointments on Windows Mobile-powered devices to display incorrect times for March 11 – April 1, 2007 and October 28 – November 4, 2007 and again in subsequent years.
Daylight Saving Time (DST) will now start three weeks earlier (2:00 a.m. on the second Sunday in March) and will end one week later (2:00 a.m. on the first Sunday in November).
