sounds like information that could be managed in the openstreetmap
database. it is after all geodata, and osm is pretty relaxed as to
what info is added

if you added a key to the wiki through the usual discussion/voting
progress and talked it up on the osm-talk mailing list, i bet you
could have it populated very quickly, and it would be a very
non-restrictive license

how many discrete time zones are there after all? can't be more than 100?

i understand william's reticence, but so long as the data is kept up
to date and/or there's a way to override it, there should be no
problems - nz dst has changed again recently and the some older phones
have had some problems, so i know where he's coming from
