title: 'Series' object has no attribute 'datetime'
body: <p>I am trying to convert a column of timestamps (YYYY-MM-DD HH-MM-SS)from a pandas df to seconds. </p>
  
  <p>Here is my current code: </p>
  
  <pre><code>df['recorded_time'] = pd.to_datetime(df['recorded_time'])
  df['timestamp'] = df['recorded_time'].datetime.total_seconds() #creating a new column
  </code></pre>
  
  <p>The error I keep getting is: </p>
  
  <p><code>AttributeError: 'Series' object has no attribute 'datetime'</code>.</p>
  
  <p>Can anyone point out where I may be missing a step? </p>
