SYMPTOMS

U.S. daylight saving time zones change in 2007. However, these changes do not occur on the correct day on Microsoft Windows CE 5.0-based devices. Windows CE 5.0 changes the time on the first or last Sunday of the month. Windows CE 5.0 does not change the time on the second or third Sunday of the month.

CAUSE

This problem occurs because the Time Service in Windows CE 5.0 does not support the new U.S. time zone change. The code that reads the time zone assumes that the change occurs on the first or last Sunday of the month. However, the new U.S. time zone update occurs on the second Sunday of the month.
