Daylight Saving Time's Y2K7 Problem

In 2007, Daylight Saving Time will start on the second Sunday in March (March 11, 2007) instead of the first Sunday in April (April 1, 2007). Desktop OS's patch themselves all the time, so the new DST rules taking effect next year won't have much of an impact on your PC. But many systems—including routers, servers, and mobile devices—don't change often if at all. It could be a bumpy three weeks.

Problems Affecting Java Applications:

The Java Runtime Environment (JRE) stores rules about DST observance all around the globe. Older JREs will have outdated rules that will be superseded by the Energy Policy Act of 2005. As a result, applications running on an older JRE may report incorrect time from March 11, 2007 through April 2, 2007 and from October 29, 2007 through November 4, 2007.

URGENT Actions Required: Changes to Daylight Saving Time will affect IBM WebSphere Application Server and its associated Operating Systems:

Any US time zone based application which uses time will be affected, in particular during the additional weeks of extended Daylight Saving Time in March and November starting in 2007
