title: How to convert a CharField to Datetime Field in Python(Django)?
body: <p>I have a CharField in my model as well as my database. I want to convert this CharField column to real datetime Django format. I have this insert query like </p>
  
  <pre><code>test.objects.create(voice=m.voice, size=m.size, start_time=get_time.get('min_time'),)
  </code></pre>
