title: Python's timedelta: can't I just get in whatever time unit I want the value of the entire difference?
body: <p>I am trying to have some clever dates since a post has been made on my site ("seconds since, hours since, weeks since, etc..") and I'm using datetime.timedelta difference between utcnow and utc dated stored in the database for a post.</p>
  
  <p>Looks like, according to the docs, I have to use the days attribute AND the seconds attribute, to get the fancy date strings I want. </p>
  
  <p>Can't I just get in whatever time unit I want the value of the entire difference? Am I missing something? </p>
  
  <p>It would be perfect if I could just get the entire difference in seconds.</p>
