title: Python- postgresql timestamp and time without time zone
body: <p>I have 2 strings which represent:</p>
  
  <ol>
  <li>date- <strong><em>dd/mm/yyyy hh:mm</em></strong> and I need to convert it to <strong>timestamp without time zone</strong> </li>
  <li>start_time/end_tiime- <strong><em>hh:mm:ss</em></strong> and I need to convert it <strong>time without time zone</strong></li>
  </ol>
  
  <p>I need to do this in order to add them to a sql query. which looks like this:</p>
  
  <pre><code>sql = '''
      INSERT INTO myTable (date, start_time, end_time)
      VALUES (%s ,%s, %s, %s);'''
  params = [timestamp, start_time, end_time]
  self.cursor.execute(sql, params)
  </code></pre>
