proposed time zone package changes

I object to adding Geneva.

The rule has always been to only add new IDs when they are distinct after
Jan 1, 1970. This does not appear to meet that criterion. As a matter of
fact, not so long ago some IDs were dropped precisely because they did not
meet that criterion.

(If we added any and all IDs without a cutoff date, we would have a
disastrous blowup in the number of IDs.)
