Oh, new variant of this INVALID bug. getYear() method is behaving according to
spec. (see ECMA Edition 3, 13 October 1999 - Section B.2.4) -- it SHOULD return
03 for 2003.

but! if looked up the 'official' specs:

http://developer.netscape.com/docs/manuals/js/core/jsref/date.htm#1194138:

getYear is no longer used and has been replaced by the getFullYear method.

The getYear method returns the year minus 1900; thus:

    * For years above 2000, the value returned by getYear is 100 or greater. For
example, if the year is 2026, getYear returns 126.

    * For years between and including 1900 and 1999, the value returned by
getYear is between 0 and 99. For example, if the year is 1976, getYear returns 76.

    * For years less than 1900 or greater than 1999, the value returned by
getYear is less than 0. For example, if the year is 1800, getYear returns -100.

To take into account years before and after 2000, you should use
Date.getFullYear instead of getYear so that the year is specified in full.

so this is INVALID.

Verified Duplicate.

See bug 45764 for the history of this method, and how Mozilla and
Microsoft came to differ on its behavior. 

At any rate, the method to use is getFullYear().
