What I'd really like to see is a separate document defining
globally-scoped timezone names.  That way, TZIDs don't have to be
arbitrary.  I would think that such a document would want to use a
subset of the names in the Olsen database.  e.g. "/US/Eastern"

I agree that this would be useful.

These also seem appropriate.
