IBM Time Zone Update Utility for Java™ - Download page
The IBM Time Zone Update Utility for Java (JTZU) applies DST changes
directly to your Java SDKs and JREs.
JTZU version 1.6.9p
JTZU updates the time zone information in IBM-supplied releases and service refreshes
of the Java SDK and JRE. With this tool, you can adopt changes to DST when you are unable
to apply a service refresh, or when a service refresh is not yet available that incorporates
the time zone changes you need.
JTZU searches your system for IBM SDKs and JREs and updates each one found.
The tool works in two modes:
Discovery mode identifies the Java instances that need updating and produces
a detailed log file, which includes the current time zone levels.
Patch mode updates Java instances to apply the DST changes. You must stop your
Java applications when this process is running.
You can use JTZU to update individual Java instances or multiple instances on
local or network drives. The update process can be run automatically without user
intervention, or you can control which JREs and SDKs are updated. The flexibility
built in to the tool means that you can adapt the way it runs to suit your needs.
For further information about downloading, installing, and using JTZU, see the
Readme file.
JTZU v1.6.9p delivers time zone changes for:
America/Argentina/Buenos_Aires
America/Argentina/Cordoba
America/Argentina/Tucuman
America/Argentina/San_Luis
JTZU is supported on AIX, Solaris, HP-UX, Linux, Windows, i5/OS and z/OS.
For more detailed information about the platforms supported and the SDKs and
JREs discovered and updated by JTZU, see the Readme file.
Warning - Applying IBM product maintenance that contains earlier time zone data
will remove the updates applied by this tool. You must rerun this tool to restore the time
zone data to the latest level. Updates made to Java time zone data by JTZU are not managed by any
of the formal change control mechanisms for servicing IBM software products.
For technical support on JTZU, including questions or feedback, send an
e-mail to jtzu@uk.ibm.com.
This address is monitored on weekdays during normal working hours.
We aim to reply within two working days.
If you have a licence that includes product support, you can also report
problems using the standard IBM product support process. You must identify
the IBM product being updated when the problem occurs.
