Don't appear where? /usr/share/zoneinfo/ has a number of subdirectories.
`ls -R /usr/share/zoneinfo/` for a full list of files.

I believe that the zoneinfo database is the only centralised source  
for timezone & global daylight-savings information. I'd doubt that  
Apple (or Microsoft or anyone else) would be getting their  
information from anywhere else.

In my mind the question is whether Mac OS respects the contents of / 
etc/localtime or whether the symlink is merely created for the  
benefit of 3rd-part *nix programs when you set the timezone in the  
GUI (and stored elsewhere for the benefit of MacOS itself).
