Reproducible: Always
Steps to Reproduce:
1.Save the above as a web page and view it.
2.JavaScript will run on load and error message will show what getYear() returned.
(Verified that IE doesn't trip over this)

Actual Results:  
Alert box shows
 Invalid Year: 2004
 Maxyr: 104
 today: Wed Jul 14 2004 15:35:22 GMT-0400 (Eastern Daylight Time)

Expected Results:  
The alert box shouldn't show, because maxyr should be 2004.
It's supposed to return 104.  Use getFullYear to get your desired result.

IE is doing it wrong.
