Starting in 2007, in line with the Energy Policy Act of 2005, there are new changes in when daylight savings time starts. In the United States, DST now begins on the 2nd Sunday of March, and ends the 1st Sunday of November.
For most people running micro$oft windows, you can go to support.microsoft.com and automatically download a patch to implement the new changes to your computer. For those using older windows, e.g., windows 98, there is no support as microsoft has stopped supporting these operating systems a while back.
