To be precise, ZIUpdater works as a JAR file utility that operates against the Java installation of the JRE that invokes it. It compiles tzdata source information into files in binary format and puts these files into the Java installation directory.
ZIUpdater can be used with the any version of time zone database available from IANA. See Using the Time Zone Updater Tool for details.
$JAVA_HOME/bin/java -jar ziupdater.jar -l file://[path]/tzdata.tar.gz
For more information on how to run ZIUpdater, current version details, and other notes, please refer to the enclosed README file and Using the Time Zone Updater Tool.
As a reminder, please note that every Azul Platform Core and Azul Platform Prime release ships with the latest IANA time zone data files available at the time of release. Therefore updating your JDK/JRE and using ZIUpdater remain complementary actions; both are suitable tactics to ensure you are using the latest time zone definitions.
