How do you retrieve the client user's time zone for a web application?

Question

The question is as it sounds - how to retrieve the client user's time zone based on their browser input? If it matters, server side, J2EE is used - but I don't think that really matters in this case. Right now, HTTP is the protocol, it may use HTTPS when it goes live.
