To be logical about date (I won't defend the use of date here, just if
it is being used) you could checkout by date:
  svn co -r '{2007-04-13}' 

and then you can check which revid svn has given it with svn info if you
want to include the revid as part of the release tag.

Or we could amend the guidelines to say date of commit.  The guidelines
actually mean:
date-which-I-can-tell-the-revision-control-system-so-I-can-get-the-same-checkout-you-did

which is date of checkout when you checkout HEAD.
