That'd be news to me.  Good news.  Can you give URLs for this?

I just now Googled for New_York.geo, but all I found was Doug Royer's
expired draft proposal for a registry for such data
<http://ietfreport.isoc.org/idref/draft-royer-timezone-registry/>.  As
far as I know, this has not been implemented.  I have seen technical
recommendations for a time zone service that might contain the data
you're talking about
once it gets implemented.

Some timezone area data is mentioned under "Time zone boundaries" in
<http://www.twinsun.com/tz/tz-link.htm>.  You can look there, but I
suspect it won't be exactly what you want.
