Google Analytics Code Difference?

[Nblufire12]

Hey guys

I was sifting through a websites Source Code and saw this Analytics Code:

<script src="http://www.google-analytics.com/urchin.js" type="text/javascript">
</script>
<script type="text/javascript">
_uacct = "UA-403065-1";
urchinTracker();
</script>


It looks a lot shorter and different from mine, why?

<script type="text/javascript">
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
document.write(unescape("%3Cscript src='" + gaJsHost + "google-analytics.com/ga.js' type='text/javascript'%3E%3C/script%3E"));
</script>
<script type="text/javascript">
try {
var pageTracker = _gat._getTracker("UA-5164698-44");
pageTracker._trackPageview();
} catch(err) {}</script>
