title: Ruby 2.2.2 - Time zone reference
body: <p>I just upgraded to Ruby v 2.2.2.</p>
  
  <p>Now, when I start my console, I get this error:</p>
  
  <pre><code>.rvm/gems/ruby-2.2.2/gems/activesupport-4.0.2/lib/active_support/values/time_zone.rb:282: warning: circular argument reference - now
  Loading development environment (Rails 4.0.2)
  </code></pre>
  
  <p>I don't know what it means or how to fix it. I don't have a file called time_zone.rb in my application, so I assume its something that is incorporated by reference.</p>
  
  <p>Does anyone know what to do to resolve this?</p>
