instance method 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
