title: Convert timefield to 24hours in django
body: <p>I have a field 
  Time = models.Timefield</p>
  
  <p>Which gives output as for example 8:30 am
  But I want 08:30:00 how can I get it?</p>
  
  <pre><code>&lt;!DOCTYPE html&gt;
  &lt;html lang="en"&gt;
  &lt;head&gt;
  &lt;meta charset="UTF-8"&gt;
  &lt;title&gt;Title&lt;/title&gt;
  &lt;/head&gt;
  &lt;body&gt;
  {{ time }}
  {{ time.start}} {{time.end}} # this prints as 8:30 am but I need 08:30:00
  
   &lt;/body&gt;
    &lt;/html&gt;
  </code></pre>
