Quoting the [Joda-Time documentation](http://joda-time.sourceforge.net/apidocs/org/joda/time/format/DateTimeFormat.html):

> Zone names: Time zone names ('z') cannot be parsed

So, unless you can hardcode the timezone in the date filter configuration I think you need to translate the timezone names into offsets and include the offset in the timestamp to be parsed.
