"x Days ago' template filter in Django?

I'm looking for a filter that turns a datetime instance into 'x Days' or 'x years y months' format (as on SO). Suggestions? Am I overlooking something very obvious?

From stackoverflow

• Have a look at the timesince template filter. It's builtin.

  The following returns a humanized diff between now and comment_date (e.g. '8 hours'):

  {{ comment_date|timesince }}
  

  The following returns a humanized diff between question_date and comment_date:

  {{ comment_date|timesince:question_date }}
  

  Yuvi : Thanks, just what I was looking for :) /me should've read the docs better
