Subject: Test cases for zoneinfo data

Hi there,

I'm creating a set of Java classes that closely reflect the structure of the 
Zoneinfo database. My requirement is driven mostly by wanting to 
dynamically update Java TimeZone classes i.e. as opposed to compiling a 
zoneinfo data and re-starting my application. In addition I feel that the 
ICU and Sun classes do not accurately reflect Zoneinfo structures.

I shall open-source this project once it gets to a working point.

It'd be terribly helpful if I could get hold of some test cases, automated 
or otherwise, that verify correct time zone calculations. Would anyone 
out there have such things?

Kind regards,
