December 2007 cumulative time zone update for Microsoft Windows operating systems

Important 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.

Do we in the UK need to do anything about this, or should we wait for the normal updates when they arrive? :D

Yes, just wait and see.

What about us in Asia, Pat Willener. I think we agreed before that if the country where you're based doesn't have DST, all these updates can be ignored. Does that still hold in your view?

Windows XP contains one module that controls time zones and DST adjustments called 'tzchange.exe' (in Vista and 2003 it is two or three modules involved). This program is already in Windows, and it has certain values set. KB933360 updated these values, and this latest KB updates it again.

My view is that we may as well have the program that has the latest, correct TZ information, even if we are not personally affected by it.

OK, thanks for the advice.
