title: Guzzle 6 - Get request total time
body: <p>I'm searching to retrieve the request total time in Guzzle 6, just after a simple GET request :</p>
  
  <pre><code>$client = new GuzzleHttp\Client();
  $response = client-&gt;get('http://www.google.com/');
  </code></pre>
  
  <p>But can't find anything in the docs about that. Any idea ?</p>
  
  <p>Thanks a lot.</p>
