How to Use the TZUpdater "-l" Option to Add New Timezone Data to JDK or JRE Installations (Doc ID 1999305.1)

Last updated on APRIL 13, 2023

Applies to:

Java SE JDK and JRE - Version 7 and later
Information in this document applies to any platform.


You may have noticed that Oracle no longer provides a new TZUpdater tool update for every timezone update from the Standards body, ICANN / IANA.  This is because, in 2015, Oracle released TZUpdater version 2.0, which provides a new feature to access the latest timezone data directly from IANA or ICANN.  You no longer need to wait for a new version of the TZUpdater tool in order to add new timezone data to your JDKs.  Now, you can use the same TZUpdater version and simply use the new "-l" feature to get timezone updates directly from IANA or ICANN as soon as they release them.

This document gives an example on how to use this new "-l" option.

There will, of course, be updates to TZUpdater for bug fixes and improvements of the tool itself, and so you should always use the latest release of the tool to take advantage of those improvements.   Download the latest TZUpdater version from Document 1439822.1 Supported Java SE Downloads on MOS.
