title: descriptor 'time' of 'datetime.datetime' object needs an argument
body: <p>I have a file sorted per date / time in csv form, eg below,  upon which I am making calculations. I want my code to cease calcs for that day once a certain time has passed. eg, no more calc if Time > 20:00. the time every day does not change.  Data example:</p>
  
  <pre><code>Date        Time        Open    High    Low    Close    Volume
  02/01/2015  14:30:00    111.39  111.44  111.2   111.24  707185
  02/01/2015  14:31:00    111.24  111.3   111.14  111.3   286506
  </code></pre>
  
  <p>I have tried to define an endTime, then I say when time > endTime... suggestions appreciated..</p>
  
  <pre><code>endTime = datetime(int(datetime.now()), int(datetime.now()), int(datetime.now()), 15, 30, 00)
  TypeError: int() argument must be a string or a number, not 'datetime.datetime'
  
  endTime = datetime.time(hour=20, minute=00, second=00)
  TypeError: descriptor 'time' of 'datetime.datetime' object needs an argumen
  </code></pre>
