GoogleTimezone

Small gem to get timezone info by known coordinates using google timezone api.

Installation

Add this line to your application's Gemfile:

gem 'google_timezone'

And then execute:

$ bundle

Or install it yourself as:

$ gem install google_timezone

Usage

You can pass latitude and longitude to gem in several ways: with array or separated values.

GoogleTimezone.fetch([latitude, longitude]) 
GoogleTimezone.fetch(latitude, longitude) 

Any other options which are described in google's documentation you can pass via options hash

GoogleTimezone.fetch(latitude, longitude, language: 'en', signature: 'key')

It uses latitude and longitude to retrieve timezone info.

result = GoogleTimezone.fetch(50.1196004, 8.679918299999999)
result.time_zone_name => 'Europe/Berlin'

It will get GoogleTimezone::Result object which maps major google api responce items named in snake case. More information here Also there is GoogleTimezone::Result#success? method. It returns true if responce was successful.

The bang version fetch! raises an GoogleTimezone::Error exception with error message if response from Google wasn't success.

Usage in tests/specs

During tests, you probably don't want to make remote calls. To achieve this, you should set a default stub in your test/spec helper file, e.g.:

# spec/support/google_timezone.rb
GoogleTimezone.set_default_stub(
  'dstOffset' => 3600,
  'rawOffset' => -10800,
  'status' => 'OK',
  'timeZoneId' => 'America/Sao_Paulo',
  'timeZoneName' => 'Brasilia Summer Time'
)
