You're assuming that a Date has a time zone to start with. It doesn't. A Calendar does, but a Date is just milliseconds since the Unix epoch. It doesn't know about calendar systems or time zones. It's just a point in time.

It's not clear what you want to do with the result - but if it's a matter of formatting it for display, just use SimpleDateFormat and set the time zone on that instead.

I would also strongly recommend that you use Joda Time instead of the built-in types... it's a much more sensible API.
