By the Java SE Platform Support Team, Jun 2013  
 

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.
