These copyright notices are mostly-useless boilerplate anyway, but if you're going to have one, it should have specific, fixed dates, not dynamic ones as this site suggests [1].<p>As a thought experiment: if a date is not actually in the document, but is updated dynamically by the document, what legal purpose could it serve? It seems an exhibit with no more legal relevance than a pocket watch.<p>[1] <a href="http://stackoverflow.com/a/2391555/4323" rel="nofollow">http://stackoverflow.com/a/2391555/4323</a>
