This table shows which version of the Timezone data is included in the different releases of the Java Development Kit (JDK) software and the TZUpdater tool. Further information about the contents of the timezone data releases is contained in the related request for enhancement (RFE) for that release. Where a major timezone change has been included in a timezone data release, this is described in the last column.
Latest TZdata release can be found from IANA TZdata page.
Since the release of TZUpdater v2.0, users can now update the tzdata version in their JDK/JRE using data obtained directly from the IANA tzdata releases. Refer to the TZUpdater README for more details.
