Microsoft Time Zone Editor

In many countries, the start dates and end dates for daylight saving time (DST) change from year to year. Additionally, countries may change their policy of recognizing daylight saving time, or they may change the local time offset from Coordinated Universal Time (UTC). This article contains information about how to update the registry in Microsoft Windows so that it accommodates these types of ongoing changes. All computers should be updated with these time zone updates, regardless of whether they are located in a changing time zone, because some applications may use the local time zone database to perform date and time calculations for events elsewhere in the world.

The samples in this article update a Windows-based computer to the global time zone rules that are used in Windows as of December 2007. This article discusses how to configure the changes that are described in the following Microsoft Knowledge Base article:
