UsTimeZones

This gem takes in a set of coordinates and returns a US time zone as long as the input coordinates are in the US. The gem should therefore be used in conjunction with other time zone APIs to ensure international coverage. The US’s time zone boundaries are surprisingly unusual, and the Google Maps time zone API, as well as other APIs I have tested, do not perfectly account for some of the more esoteric boundaries.

Installation

Add this line to your application's Gemfile:

gem 'us_time_zones', '~> 2.0.9'

And then execute:

$ bundle

Or install it yourself as:

$ gem install us_time_zones

Usage

TZ.whichTZ?([LAT, LNG]) #==> returns US TIME ZONE

Example: TZ.whichTZ?([33, -84]) #==> returns “US Eastern Time Zone”

If outside the US: ==> returns "Unable to determine time zone for coordinates outside the US" OR ==> returns “Error”

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake false to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
