title: Trying to mock datetime.date.today(), but not working
body: <p>Can anyone tell me why this isn't working?</p>
  
  <pre><code>&gt;&gt;&gt; import mock
  &gt;&gt;&gt; @mock.patch('datetime.date.today')
  ... def today(cls):
  ...  return date(2010, 1, 1)
  ...
  &gt;&gt;&gt; from datetime import date
  &gt;&gt;&gt; date.today()
  datetime.date(2010, 12, 19)
  </code></pre>
  
  <p>Perhaps someone could suggest a better way?</p>
