The Theory change reinstates the one zone per ISO-3166 region requirement. I'm afraid that's incorrect. That change would strengthen the requirement beyond what it ever was, by requiring a Zone to be present for every country. That has never been required and has never been the practice in the tz database.
Since the ISO-3166-1 code table is a reasonably well used base for most geographical activity, at some point timezones are required to match each. As with pre-1970 data, this creates a new 'second database' requirement in providing that mapping, and personally I see no reason that it should not be covered by the main database. Moving on to 3166-2 and -3, the ISO have already solved that problem for us since that data is chargeable, so until such time as a freely available list is made available we are required to provide our own sub-zones where necessary anyway :) -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
