In my template i need to make `1255992517000` to an date-time. i tried `{{note.created|date:"U"}}` and `1255992517000|date:"U"` but it didn't work. How to get it to work? From [django docs](https://docs.djangoproject.com/en/dev/ref/templates/builtins/?from=olddocs#std:templatefilter-date) one can see it should work, but how?
