I have read at several websites about there being time zone area polygon lists. For example a file called New_Yok.geo.
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 <http://www.calconnect.org/publications/timezoneregistryandservicerecommendat...>, once it gets implemented.
So can you please direct me to where I can download the timezone area polygons.
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.
