Just to add to Andy's note, this code snippet, which should go in your
theme.php, applies the nice_date function when echo $post->pubdate_out
is called in your template. The final string indicates how the date
will be formatted. See http://au2.php.net/date for a list of the
parameters that can be used here.
You can format dates differently with different hooks. For example, if
you want to format dates on comments you'd change 'post_pubdate_out'
to 'comment_date_out' (I think, I didn't look that hook up).

Well, not strictly on your own, you just have to be patient :)
