INTRODUCTION

This article describes how the February 2007 cumulative time zone update for Microsoft Windows operating systems affects the Antigen and Forefront products that are listed in the "Applies to" section.

MORE INFORMATION

Beginning in 2007, daylight saving time (DST) will be extended in the United States and in Canada. DST will start three weeks earlier than in previous years, on March 11, 2007. DST will end one week later than in previous years, on November 4, 2007.

This condition results in a new DST period that is four weeks longer than was previously observed. Unless certain updates are applied to your computer, the time zone settings for your computer's system clock could be incorrect during this four-week period. In particular, you must make sure that both Windows and your calendar programs are updated.

We have tested the products that are listed in the "Applies to" section together with the Microsoft Windows Server DST updates. We have verified that these products and the Windows Server DST updates are compatible.

For more information about DST updates, visit the following Microsoft Web site:

Community Feedback System

Very often, it takes hours to solve a problem. Very often, you've looked high and low, and have tried a lot of solutions. When you finally found it, chances are, it was because someone else helped you. Here's your chance to give back. Use our community feedback tool to let others know what worked for you and what didn't.

Please also understand that the community feedback system is not warranted to be correct, it's simply a system that we've built to let people try and help each other. If something in a feedback response doesn't make sense to you, or you're not comfortable making changes that the feedback talks about (like registry edits), please consult a professional.

Thank you for using kbAlertz.com Feedback System.
