Java SE team has come out with the TZupdater tool some time back. This TZupdater tool is provided to allow the updating of installed JDK/JRE images with more recent timezone data in order to accommodate the U.S. 2007 daylight saving time changes (US2007DST) originating with the U.S. Energy Policy Act of 2005.
This tool is available now for download from the Sun Java SE download site.
For more information, check out the README file.
Note: This tool is currently a Beta release.
