Timezone Data Versions in the JRE Software

Print-friendly Version

This table shows which version of the Olson 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 Olson releases is contained in the related request for enhancement (RFE) for that release. Where a major timezone change has been included in an Olson release, this is described in the last column.
