 Advisory Information

LAST UPDATE: 2007-11-02
v 2.0


This second edition of this Engineering Advisory (EA) releases a corrected V5.1B-4 version of the Early Release Patch (ERP). The earlier V5.1B-4 version did not contain the timezone changes for Western Australia and Canada.

The ERPs identified in the Resolution section of this Engineering Advisory provide the HP Tru64 UNIX modifications necessary to address changes to the daylight saving rules. The V5.1B-4 and V5.1B-3 kits introduce changes for systems in New Zealand.

The ERP kits also contain the previously released 5.1B-4 and 5.1B-3 time zone changes for the United States, Australia (for both the Commonwealth games, and Western Australia), Bermuda, Brazil, Canada, Uruguay, and the Bahamas.


The following versions are affected:

  • HP Tru64 UNIX V5.1B-4
  • HP Tru64 UNIX V5.1B-3

HP is releasing the following ERP kits publicly for use by any customer. The ERP kits use dupatch to install and will not install over any Customer Specific Patches (CSPs) that have file intersections with the ERP. Contact your service provider for assistance if the installation of an ERP is blocked by any of your installed CSPs.

The fix contained in these ERP kits is targeted for availability in the following mainstream patch kit:
