问题
I'm looking for a list of timezones with polygon lat/lng information. I want to build a tool that I can punch in a lat/lng and spit out a timezone. Basically the same thing that Geonames and EarthTools does except that I don't want to have to make a web service call or depend on a third-party service with request limits.
Any suggestions on where I can find this data?
