getFullYear( )

Dup of Bug 22964 'JavaScript: getYear returns "100" for 2000'

firefox should return 05 instead of 105. i think thats what the bug is. and ive
repoduced this bug too.

Comment 3

[Grayson Mixon (ColdFusion650)]

if getYear() is deprecated, and firefox is standards compliant, why do they
still support?

Comment 4

[Doug Wright]

re comment #2 - no it shouldn't. getYear is defined in ECMA-262 as years since
1900, not 'last 2 digits of year'.

re comment #3 - just because it is old and flawed, doesn't mean it isn't part of
the standard.

on bug 22964, the guy says the getYear() was deprecated. that means its no
longer part of javascript. so firefox shouldnt support it at all.

ok guys, research shows that getFullDate should be used and not getDate and 
getFullDate returns the correct year in Firefox.
