As many of you know, Daylight Savings Time (DST) in the United States is changing this year to start on March 11th, 2007 (3 weeks earlier than normal) and end on November 4th, 2007 (1 week later than normal). I thought I would write a quick post on the impact of these changes on SQL Server.
SQL Server Engine, Analysis Services, etc. uses/relies on Windows for many date/time functionalities, so if you have the proper updates for Windows there should be no noticeable issues. You can find the proper updates for Windows at this KB article
There are other perceived DST issues for SQL Server that have been around that are not specific to the 2007 change but you may perceive them to be related. You can read about these issues at this KB article
