Since various browsers will return either
100, 1900 or 2000 and we always want 2000
it may be best to just make a function
like the following(and note use of % operator
which gives a remainder after dividing):

//the following function only gives a result from 1950 to 2049
function getYear4(aYear){
var vYear=parseInt(aYear);
var v1950to2049=0;
if (vYear % 100 < 50 ) {
v1950to2049=(vYear % 100) + 2000
} else {
v1950to2049=(vYear % 100) + 1900
};
return v1950to2049;
};

//then using the function
var date= new Date(Date.parse("01/01/1900"));
document.write=("Year is " + getYear4(date.getYear()) + "" );

Even though getYear is 1900, above writes out:
Year is 2000
