If you've got some older systems or a new netbook that can't quite handle Vista , you might be hanging onto Windows XP longer than you thought.
Out of the box, XP and the new DST changes don't get along.
As a result of The U.S. Energy Policy Act of 2005, the United States has an extended daylight saving period that lasts 3-4 weeks longer than in years prior to 2007.
But there's a fix!
There's a handful of ways to update your computer so that it supports the new DST dates:
- Downloading an EXE update
- Manual registry changes
- TZEdit and some others...
For a single machine, I found the most straight-forward way to update your machine is through TZEdit.
- Download TZEdit.
- Run TZEdit.exe to extract it to the default directory (C:\Program Files\TZEDIT).
- Run C:\Program Files\TZEDIT\TZEdit.exe.
- The timezone configured on your machine should be automatically selected.
- Click the Edit button.
- Change the Start Day to the Second Sunday of March at 2:00am.
- Change the Last Day to the First Sunday of November at 2:00am.
- Click OK.
- I found to get the settings to stick I had to change time zones in the Date and Time Properties window (the window that pops up when you double-click the time in the tray). Change to some other time zone, and then change back to your original time zone.
- Now reboot.
- To test, change your date/time to the second Sunday of March at 1:59:59am. If all went well, you should "spring" forward to 3:00am.
