(Firefox :: General, defect)

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; pl-PL; rv:1.7.5) Gecko/20041108 Firefox/1.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; pl-PL; rv:1.7.5) Gecko/20041108 Firefox/1.0

In the right frame there is such a script:
	<SCRIPT TYPE="text/javascript">
	<!--
	var montharray=new
Array("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");
	function countup(yr,m,d)
		{
		var today=new Date();
		var todayy=today.getYear();
		var todaym=today.getMonth();
		var todayd=today.getDate();
		var todaystring=montharray[todaym]+" "+todayd+", "+todayy;
		var paststring=montharray[m-1]+" "+d+", "+yr;
		var
difference=(Math.round((Date.parse(todaystring)-Date.parse(paststring))/(24*60*60*1000))*1);
		difference+="</B> dni!<BR>";
		document.write("Witryna założona 18 czerwca 2002 roku, istnieje już
<B>"+difference);
		}
	countup(2002,06,18);
	//-->
	</SCRIPT>
It leads to bad results in Mozilla and Mozilla Firefox. Interesingly that the
script works properly in Opera (and of course in MSIE).

The text as seen in the browser is: "Witryna założona 18 czerwca 2002 roku,
istnieje już -693005 dni!", it means "the website is created on 18th June 2002,
it has already existed ... days"


Reproducible: Always

Steps to Reproduce:
1. See Details above.
2.
3.

Actual Results:  
See Details above.

Expected Results:  
It should show the correct number of days like Opera or MSIE do.

The bug is configuration-independent.

Read bug 22964, comment 2 for an explanation why getYear return 105 and not 2005

use getFullYear() instead.
