Ruby gem for finding timezone of location [closed]

Answer 1

You can easily get a latitude and longitude using the google maps geocoding API. There are ruby implementations for the API like GeoKit. Once you have that you can use the timezone gem to easily get the timezone of a latitude and longitude. The gem makes it easy to do time conversions in your timezone as well.

Here is an example using GeoKit and TimeZone.

require 'geokit'
require 'timezone'

res = Geokit::Geocoders::GoogleGeocoder.geocode('140 Market St, San Francisco, CA')
timezone = Timezone::Zone.new(:latlon => res.ll)

timezone.zone
=> "America/Los_Angeles"
timezone.time Time.now
=> 2011-12-01 14:02:13 UTC
