The tzupdater 2.0.0 tool allows you to update installed JDK and JRE images with the most recent time zone data to accommodate daylight saving time changes in different countries. Oracle relies on the time zone data publicly available through IANA's Time Zone Database.

The U.S. official DST changes are:

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

For Java:

  • JDK 8.0.0 or later, JDK 7.0.0 or later, JDK 6.0.0 or later, JDK 5.0.03 or later support the US Daylight Saving Time (DST) change
  • JDK 8.0.0 or later, JDK 7.0.0 or later, JDK 6.0.0 or later, JDK 5.0.05 or later support the Canada DST changes

In addition, the tzupdater time zone update tool was released, giving customers the most flexibility in updating 5.0, 6.0, 7.0, and 8.0 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 daylight saving time changes in different countries. Oracle relies on the time zone data publicly available through IANA's Time Zone Database.

HPE recommends utilizing the latest HPE Java SE 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 use the latest HPE JDK/JRE update release, this tool provides a means of updating time zone data while leaving other system configuration and dependencies unchanged.

The tzupdater tool supports all HPE JDK/JRE for 5.0.x/6.0.x/7.0.x/8.0.x versions on supported platforms.  Also see the HP-UX 11i Java tzupdater Release Notes listed under "Getting started" on the HPE Support Center at http://www.hpe.com/info/java.
