Two problems:
- one language product with two sources of time information - no
wonder the OP is confused why their time is wrong: perhaps you could
post how the OP can correct their Joda time, walk them thru difficulties
that may be encountered in http://www.joda.org/joda-time/tz_update.html;
- Joda time says the project is finished, and advises migration to Java
SE 8 java.time, so it may not be reasonable to expect prompt future
releases or tz updates.

Like Adobe products, Java has become such a source of security holes and
vulnerabilities requiring frequent updates, blocked by various products,
that it's safer to uninstall them, eliminate the annoyances and
vulnerabilities, and do without what they provide, or use alternatives
that don't suffer the same issues.

Take care. Thanks, Brian Inglis, Calgary, Alberta, Canada
