This update supersedes and replaces update 933360, which was released in August 2007. This update also includes additional time zone changes that were signed in to law after update 933360 was created. If you have already deployed update 933360, read the descriptions of the specific time zone changes that are addressed in this Microsoft Knowledge Base (KB) article to determine whether you must deploy this update immediately. If systems are not directly affected, you can schedule deployment at the next available opportunity. We recommend that you deploy the most current Windows cumulative time zone update to guarantee the consistency of the time zone database on all systems.
