Because of the Energy Policy Act, daylight saving time is extended by four weeks in 2007 in United States and Canada. To fix this issue in Windows Mobile, Microsoft has published KB923953 which provides updated registry key information for OEM device manufacturers who can use the listing to create an .inf file that is contained in a .cab file. The .cab file can then be installed in Windows Mobile-based devices. But many device manufacturers haven’t yet released this update and it is a pain to manually add the registry information by hand.
