Ah - I certainly didn't know about this so thanks for the "heads-up". At first glance though, I don't see that Zoneinfo's structures are being faithfully reproduced here. I suppose another motivation for me was to stick to the Zoneinfo structure given that it is highly evolved and flexible. Please see the attached class diagram of what I'm working to and do feel free to voice your opinion. ZoneinfoTimeZone is a JDK compatible TimeZone facade whereas the rest are intended to represent Zoneinfo structures in an object oriented manner.
