title: Python - How to convert datetime data using toordinal considering the time
body: <p>Let's assume that I have the following data:</p>
  
  <p><code>25/01/2000 05:50</code></p>
  
  <p>When I convert it using <code>datetime.toordinal</code>, it returns this value:</p>
  
  <p><code>730144</code></p>
  
  <p>That's nice, but this value just considers the date itself. I also want it to consider the hour and minutes (05:50). How can I do it using datetime?</p>
  
  <p>EDIT:</p>
  
  <p>I want to convert a whole Pandas Series.</p>
