php if else show statement - date dependent like. show if date=Dec. 2, 2010 or less than?

I updated my photo-gallery framewor开发者_开发百科k recently. But I still need the old 'javascript files' in stories older than a certain date, eg: Dec. 2, 2010. (stories are in CMS/dynamic)

I was thinking of an "if else" statement, but can't get it right.

if date(Dec. 2, 2010) < CURDATE() {
                 show this (which is the older JS files) ; }
else {
                 show the new javascript files; }

I don't like having to load both of the JS files if I don't need to (for speed sake).

Thanks in advance.

<?php
if (time() > strtotime('2010-12-02')) {
  echo '<script type="text/javascript" src="/js/highslide/highslide.js"></script> 
        <link rel="stylesheet" type="text/css" href="/js/highslide/highslide.css" /> 
        <script type="text/javascript">
            hs.graphicsDir = "/js/highslide/graphics/";
            hs.wrapperClassName = "wide-border";
            hs.showCredits = false;
        </script>';
}
else {
  echo 'old stuff';
}

Something along the line of

if date(Dec. 2, 2010) < CURDATE() {
     <script src="old_js.js" />
else {
     <script src="new_js.js" />
