Here is a fun piece of computing history I just became aware of: in 2007 the Bush administration changed when DST started, and because Exchange stored event times converted to UTC Microsoft had to release an "Exchange Calendar Update Tool" to help try and fix everyone's calendars https://web.archive.org/web/20070302224145/http://support.microsoft.com/kb/930879

- About the Exchange tool After you install the DST updates for Microsoft Windows, all old appointments that occur during the DST change periods will be incorrectly displayed as occurring one hour later. This is true for both recurring and single-instance appointments. These appointments must be updated so that they will be displayed correctly in Outlook, in Outlook Web Access, and in CDO-based applications. (remote)
