US Daylight Savings Time 2007 and Sun Java JRE


US Daylight Savings Time 2007 and Sun Java JRE

I have HP SIM 5.0 SP4, OSEM, and ISEE installed.

Because of the pending DST2007, is HP coming out with upgrades to these programs since they have non-windows registered JRE ?

While most application software will use the underlying operating system for timezone information, Java, from version 1.3.1, has maintained its own timezone database. This database (as well as the operating system database) will need to be updated whenever timezone rules change.

Sun Java SE TZupdater Tool
The tzupdater tool is provided 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) originating with the U.S. Energy Policy Act of 2005. The US2007DST data changes were incorporated into the following releases: 1.3.1_18, 1.4.2_11, 5.0u7. 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 the end-user or system-administrator is unable to use the latest Sun JDK/JRE update release, this tool provides a route of updating timezone data while leaving other system configuration and dependencies unchanged.

It's a little more complicated than a JRE. HP SIM is built using JBOSS. HP SIM 5.1, announcing and releasing next week, is what will be required for the US DST 2007 changes.
