Because of the Energy Policy Act, daylight saving time is extended by four weeks in 2007. The 2007 daylight saving time implementation is as follows:
Clocks change at 02:00 A.M. local time. On March 11, 2007, clocks will move forward one hour from 01:59 A.M. to 03:00 A.M. On November 4, 2007, clocks will move back one hour from 01:59 A.M. to 01:00 A.M.
These changes are okay unless you happen to be running some technology reliant product. For example, if you had a Windows Mobile based device, the Microsoft support article (923953) that provides you with the regisitry changes that you need to make aren’t the easiest to ask your clients to run or install.
Thanks to Bill, one of the EdgeBack consultants, the registry changes needed for the Daylight Savings Time fix for Windows mobile devices is now available as a CAB file that can be installed fairly easily. I need to install this on my smartphone later this week and will update the post with appropriate results of the installation.
