title: rails DateTime.parse for DateTime posting from client from a jquery time picker
body: <p>after upgrading to Rails 3.2 and Ruby 1.9.3 
  my forms which contains a jquery date picker, stopped working..</p>
  
  <p>in my params is see the date: </p>
  
  <pre><code>"created_at"=&gt;"03/22/2013 05:28 am"
  </code></pre>
  
  <p>but if i try to parse it like so:</p>
  
  <pre><code>DateTime.parse(params[:entry]["created_at"])
  </code></pre>
  
  <p>then it returns this error:</p>
  
  <blockquote>
    <p><em>*</em> ArgumentError Exception: invalid date</p>
  </blockquote>
  
  <p>how can i parse this kind of datetime and then turn it into UTC?</p>
  
  <p>thanks</p>
