Yes, many thanks Eric! Though I think there's a slight correction needed for to extend the America/Dawson_Creek north to America/Fort_Nelson boundary, per Chris Walton: https://mm.icann.org/pipermail/tz/2011-March/016744.html

@Zoidsoft - It's not clear whether Geonames uses Eric's tz maps or not, but either way it isn't yet reporting correctly for America/Fort_Nelson:

http://api.geonames.org/timezoneJSON?lat=58.80533&lng=-122.7002&username=demo

Currently it returns America/Vancouver.

So does Google:

https://maps.googleapis.com/maps/api/timezone/json?location=58.80533,-122.7002&timestamp=1446969600

Subject: Re: [tz] efele.net/tz maps updated

I wonder if Geonames.org updated to use the new data yet?
