A tiny service for detecting timezones by coordinates so you don't need to be dependent on online ones.
Clone the repository and run the bootstrap script:
bin/bootstrap
rails s
and just pass latitude and longitude:
curl "http://localhost:3000/timezone?lat=53&lng=27"
{"timezone":"Europe/Minsk"}%
PostGIS version >= 1.5 is required.
On Ubuntu simply install required packages with apt-get:
apt-get install postgresql-9.1-postgis
On Mac you can use Postgres.app or install PostGIS using brew.
Don't forget to look through database.yml and pick right settings depending on PostgreSQL and PostGIS versions.
Ubuntu:
apt-get install libgeos-dev
Homebrew:
brew install geos
You might need to reinstall rgeo gem to make it support geos. It's possible to uninstall and install it:
bundle exec gem uninstall rgeo
bundle install
