The tzupdater 1.3.60 tool is provided to allow the updating of installed JDK/JRE images with more recent time zone data to accommodate the U.S. 2007 daylight saving time changes (US2007DST) originating with the "U.S. Energy Policy Act of 2005", DST rule changes for Morocco, Fiji, Jordan, Tocantins, and several other changes introduced in tzdata2013g.

The U.S. official DST changes are:

  • Start Date: Second Sunday of March
  • End Date: First Sunday of November

For Java:

  • JDK 7.0.0 or later, JDK 6.0.0 or later, JDK 5.0.03 or later, and SDK 1.4.2.11 or later support the US Daylight Saving Time (DST) change
  • JDK 7.0.0 or later, JDK 6.0.0 or later, JDK 5.0.05 or later, and SDK 1.4.2.12 or later support the Canada DST changes

In addition, the tzupdater time zone update tool was released, giving customers the most flexibility in updating 1.4.x, 5.0, 6.0, and 7.0 JVMs with current time zone information.

tzupdater tool

The tzupdater tool allows you to update installed JDK and JRE images with the most recent time zone data to accommodate the U.S., Asia, Europe, and other locations' 2013 daylight saving time changes. This version of tzupdater delivers Olson data tzdata2013g, which includes DST Rule changes for Morocco, Fiji, Jordan, Tocantins and several other locations.

HP recommends the latest JDK/JRE update release as the preferred vehicle for delivering both time zone data updates and other product improvements, such as security fixes.   However, if the end user or system administrator is unable to update to the latest JDK/JRE release, the tzupdater tool provides a way to update time zone data while leaving other system configuration and dependencies unchanged.

The tzupdater tool supports all HP JDK/JRE for 1.4.x.xx/5.0.x/6.0.x/7.0.x versions on supported platforms.  Also see the HP-UX 11i Java tzupdater Release Notes listed under "Getting started" on the HP Support Center at http://www.hp.com/go/hpux-java-docs.
