I have one comment regarding the timezone file format.

Why not use a few of 20 remaining bytes in tzh_reserved field for a magic number that would be unique to timezone data files? 4 bytes at the beginning of the file would be great, but if you're concerned about space then 2 bytes would do the job if selected carefully.

I would like to add that we need it to be PERSISTENT: even if timezone would not exist anymore its magic number should be preserved. It makes possible to use them for database storage.
