Starting in 2007, Daylight Saving Time will be extended by 4 weeks in most U.S. and Canadian time zones. Daylight Saving Time will begin the second Sunday in March (3 weeks earlier) and will end the first Sunday in November (1 week later). This change complies with a provision of the Energy Preservation Act of 2005 and affects all U.S. time zones that observe Daylight Saving Time (DST). Many Canadian provinces that share or border these time zones have also announced plans to adopt this change.


To correct this problem:
  • Sun recommends utilizing the latest Sun Java SE JDK/JRE update release as the preferred vehicle for delivering both timezone data updates and other product improvements such as security fixes.
  • If you are unable upgrade to the latest Sun Java SE JDK/JRE. Sun does provide a "tzupdater" tool to allow the updating of installed JDK/JRE images with more recent timezone data in order to accomodate the U.S. 2007 daylight saving time changes (US2007DST).

To install and use the tool please refer to directly to the Sun website : http://java.sun.com/javase/tzupdater_README.html
