An idea Benjamin Franklin came up with more than 200 years ago and wrote the saying “Early to bed and early to rise, makes a man healthy, wealthy, and wise,” and was later implemented by William Willett, in1907 and has been changed several times up to 1966, when the Uniform Time Act was passed in the United States. Well Congress has changed the dates for Daylight Saving Time (DST) in the United States under the Energy Policy Act of 2005 starting in 2007 (If you are in IT this is the new Y2K dubbed Y2K7). Canada has adopted similar DST dates. DST dates in the United States will 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).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.

You can prevent these problems by installing three Microsoft files on your device and/or PC:
- Microsoft Windows Operating Systems Update
- Daylight Saving Time 2007 Update Tool
- Outlook Time Zone Update Tool
All users in the United States, Canada and Mexico should immediately install these updates. Users in other countries should install these updates if they travel to the United States, Canada and/or Mexico or if they make calendar appointments that include attendees that are based in the United States, Canada and/or Mexico.
Be sure to follow the step by step directions here.
If you use Microsoft Outlook to synchronize your calendar, download and run the Outlook Time Zone Update Tool.
If you do not use Microsoft Outlook to synchronize your calendar, connect your Windows Mobile device to your PC, then download and run the Daylight Saving Time 2007 Update Tool.
If you are unable to connect your device to a computer you can download and apply a CAB file directly to your device from here:
IMPORTANT: For the tool to properly update the Daylight Saving Time settings, you must manually change the time zone on your device. To properly update the Daylight Saving Time settings, you need to manually change the time zone at least once on your device.
