ActiveSupport::CoreExtensions::Time::Zones::ClassMethods

• activesupport/lib/active_support/core_ext/time/zones.rb

• current
• use_zone
• zone
• zone=

Returns Time.zone.now when config.time_zone is set, otherwise just returns Time.now.

Allows override of Time.zone locally inside supplied block; resets Time.zone to existing value when done.

Returns the TimeZone for the current request, if this has been set (via Time.zone=). If Time.zone has not been set for the current request, returns the TimeZone specified in config.time_zone.

Sets Time.zone to a TimeZone object for the current request/thread.

This method accepts any of the following:

• A Rails TimeZone object.
• An identifier for a Rails TimeZone object (e.g., "Eastern Time (US & Canada)", -5.hours).
• A TZInfo::Timezone object.
• An identifier for a TZInfo::Timezone object (e.g., "America/New_York").

Here‘s an example of how you might set Time.zone on a per request basis — current_user.time_zone just needs to return a string identifying the user‘s preferred TimeZone:

  class ApplicationController < ActionController::Base
    before_filter :set_time_zone

    def set_time_zone
      Time.zone = current_user.time_zone
    end
  end
