title: Nginx $request_time and $upstream_response_time in Windows
body: <p>I'm encountering some weirdness in my access log running Nginx on Windows.  I've included $request_time in my access log as well as $upstream_response_time (running Django as fcgi upstream).  It's my understanding that the log should represent request time in milleseconds, but it's output looks like this:</p>
  
  <pre><code>ip|date|request_time|upstream_response_time
  xx.xx.xx.xxx|[29/Jan/2013:15:29:57 -0600]|605590388736.19374237|0.141
  xx.xx.xx.xxx|[29/Jan/2013:15:30:39 -0600]|670014898176.19374237|0.156
  </code></pre>
  
  <p>Any ideas what the heck that gigantic number is!?</p>
  
  <p>Here's the full log format (I removed a few columns in teh above example)</p>
  
  <pre><code>log_format  main  '$remote_addr|$time_local]|$request|$request_time|$upstream_response_time|'
                    '$status|$body_bytes_sent|$http_referer|'
                    '$http_user_agent';
  </code></pre>
  
  <p>Using pipe delimiters.  </p>
