TimezoneAware

Timezone aware uses JavaScript to detect a user's timezone. After the user's own timezone is detected (i.e. after the first request), Time.zone is set automatically in an around_filter for each request. In your views and controllers, you can simply call Time.zone.now and know this will be in the user's local time.

Installation

Add this line to your application's Gemfile:

gem 'timezone-aware'

Add timezone-aware.js to application.js

//=require timezone-aware

And then execute:

$ bundle

Or install it yourself as:

$ gem install timezone-aware

Usage

Timezone aware automatically sets Time.zone during each request. After the JavaScript determines the user's timezone (via jstz.js), we set a cookie time_zone. Timezone aware then sets Time.zone based on this cookie in an around_filter.

Note: this is not thread safe as global Time.zone is being set for each request.

Examples

An example view: home.html.erb

The time is now <%= Time.zone.now %>

Converting time zone back and forth

Time.now.utc.in_time_zone(Time.zone)

TODO

• Add Poltergiest test cases
• Explore ways to get correct timezone on first request
• Explore ways to make thread safe
