tzinfo_js

NOTE

Rails only supports tzinfo gem of versions ~0.3.38. 1.0+ is not supported.

This gem supports both 0.3.38+ and 1.0+. The major difference is in 1.0+ data definitions are included in a separate gem, tzinfo-data.

Installation

Add tzinfo_js to your Gemfile:

gem 'tzinfo_js', github: 'riboseinc/tzinfo_js'

Usage with Rails

tzinfo_js provides .js file per TZInfo timezone, such as America/New_York.js.

<%= javascript_include_tag "tzinfo_js/tzinfo.js" %>
<%= javascript_include_tag "tzinfo_js/definitions/#{tzinfo_identifier}.js" %>

Run TzinfoJs::Registry.instance.zone_map to obtain a map from all TZInfo zone names to their corresponding TzinfoDefinition class (with their offsets and transitions). The resulting hash also maps linked_zones to the correct zone information, so you will have multiple zone names linking to the same zone definition classes.

TzinfoJs::Registry.instance.zone_map
=> {"Africa/Asmera"=>#<TzinfoJs::TzinfoDefinition:0x007ffc57404150
  @name="Africa/Asmara", @offsets=[[9332, "LMT"], [9332, "AMT"], [9320,
    "ADMT"], [10800, "EAT"]], @sorted_transitions="14424380.351944445 1
      39366.0 2 -13015698.316666666 3">, "Africa/Juba"...}

Updating timezone definitions

Simply run from this gem’s path:

rake tzinfo_js:generate
