How can I update the Java timezone information with a IANA file newer than the one used by the latest TZupdater release?

Question

The latest Time Zone Updater tool (TZUpdater) for Java contains an older timezone data file, which does not have the timezone changes for Chile scheduled for this weekend.

The IANA Time Zone DB has the latest information for the Chile time zone changes.

How can I use the latest IANA file (tzdata2013a.tar.gz) with TZupdater?

Answer 1

If your application uses Joda Time exclusively, it appears to be possible to update the DB for Joda time. But I haven't seen a sanctioned way to use a time file on the whole JVM.

However, this SF post may be helpful... I would test heavily on an IDENTICAL but disposible OS/jvm system first if you go this route.
