Time.zone=

Sets <tt>Time.zone</tt> 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)", <tt>-5.hours</tt>).
* 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 <tt>Time.zone</tt> on a per request basis and reset it when the request is done.
<tt>current_user.time_zone</tt> just needs to return a string identifying the user's preferred time zone:

  class ApplicationController < ActionController::Base
    around_filter :set_time_zone

    def set_time_zone
      if logged_in?
        Time.use_zone(current_user.time_zone) { yield }
      else
        yield
      end
    end
  end
