There are many sources for polygons for country boundaries. It would suffice to have the polygons within those countries that have multiple timezones. Mark On 6/29/06, Olson, Arthur David (NIH/NCI) [E] <olsona@dc37a.nci.nih.gov> wrote:

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/> <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...> <http://www.calconnect.org/publications/timezoneregistryandservicerecommendat...>, once it gets implemented.
The item google gave you is the site that I heard about it.
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> <http://www.twinsun.com/tz/tz-link.htm>. You can look there, but I suspect it won't be exactly what you want.
The only one that looks to have potential was the link to http://www.manifold.net/download/freemaps.html On that site they have a link to a TZ boundary database ftp://69.17.46.170/downloads/free_world/WorldTZ.zip But that link keeps timing out. i did a search for the file itself under google, and the two "mirrors" for it are down as well.
Do you happen to know how to get this file?
Thanks in advance.
