It's nice to see a fellow data user who has found TZ for much the same 
reason. I've been banging my head against this brick wall for a number 
of years now after finding genealogical data that we could not decipher 
because it did not even reference which version of TZ had been used to 
create it. At the very least there should be warnings but in addition it 
would be nice if well researched material was included by default and 
not relegated to the little used 'backzone' file. Much of my UK material 
relies on data in there which may or may not be available to the user - 
with no warning :(
