android获取经纬度blh,如何通过earthtools.org从经纬度获得TimeZone

# offset = TimeZoneFinder.gmt_offset(some_lat, some_lng)

# timezone = ActiveSupport::TimeZone[offset]

#

# timezone = TimeZoneFinder.timezoneId(lat, lng)

# Time.zone = timezone

# Time.zone.now

#

class TimeZoneFinder

attr_accessor :result

def self.gmt_offset(lat,lng)

self.new(lat,lng).find('gmtOffset').to_f

end

def self.timezoneId(lat,lng)

self.new(lat,lng).find('timezoneId')

end

def initialize(lat,lng)

uri = URI.parse("http://ws.geonames.org/timezone?lat=#{lat}&lng=#{lng}")

@result = Hash.from_xml(open(uri))

end

def find(key)

result["geonames"]["timezone"][key]

end

end
