title: Converting ISO 8601 date time to seconds in Python
body: <p>I am trying to add two times together. The ISO&nbsp;8601 time stamp is '1984-06-02T19:05:00.000Z', and I would like to convert it to seconds. I tried using the Python module <a href="https://bitbucket.org/micktwomey/pyiso8601" rel="noreferrer"><code>iso8601</code></a>, but it is only a parser.</p>
  
  <p>Any suggestions? </p>
