WHAT YOU MUST BE JOKING … a newer patch! http://support.microsoft.com/?id=931836
So companies have been testing the “old” one and now have to do it all again!
Starting in the spring of 2007, daylight saving time (DST) start and end dates for the United States will transition to comply with the Energy Policy Act of 2005. DST dates in the United States will start three weeks earlier, at 2:00 A.M. on the second Sunday in March. DST will end one week later, at 2:00 A.M. on the first Sunday in November.
The update that this article describes changes the time zone data to account for the DST change for the United States. This update also includes other DST-related changes, time zone-related changes, and settings-related changes. Some of these changes will occur in 2007. Some of these changes have occurred since the products that are listed in the “Applies To” section were originally released. The update that this article describes is a cumulative update rollup that includes all the changes that were previously released in Microsoft Knowledge Base articles 928388 and 929120. This update also describes some additional changes since the last cumulative update in Microsoft Knowledge Base article 928388.
