title: Curl command to get time taken
body: <p>I'm running a curl command:</p>
  
  <pre><code>curl -s -w "\n\n%{time_connect} + %{time_starttransfer} = %{time_total}\n\n" GET http://www.google.com
  </code></pre>
  
  <p>and the response that I'm getting is:</p>
  
  <pre><code>0.000 + 0.000 = 0.000
  
  &lt;HTML&gt;&lt;HEAD&gt;&lt;meta http-equiv="content-type" content="text/html;charset=utf-8"&gt;
  &lt;TITLE&gt;302 Moved&lt;/TITLE&gt;&lt;/HEAD&gt;&lt;BODY&gt;
  &lt;H1&gt;302 Moved&lt;/H1&gt;
  The document has moved
  &lt;A HREF="http://www.google.co.in/?gfe_rd=cr&amp;amp;dcr=0&amp;amp;ei=zWUAWsbbDabU-APf85KoBQ"&gt;here&lt;/A&gt;.
  &lt;/BODY&gt;&lt;/HTML&gt;
  
  
  0.217 + 0.416 = 0.417
  </code></pre>
  
  <p>So one thing that I'm not understanding is that why two instances of the time taken and what are they representing ??               </p>
  
  <pre><code>0.000 + 0.000 = 0.000
  
  0.217 + 0.416 = 0.417
  </code></pre>
