    File Name:          15.9.5.5.js
    ECMA Section:       15.9.5.5
    Description:        Date.prototype.getYear

    This function is specified here for backwards compatibility only. The
    function getFullYear is much to be preferred for nearly all purposes,
    because it avoids the "year 2000 problem."

        1.  Let t be this time value.
    2.  If t is NaN, return NaN.
    3.  Return YearFromTime(LocalTime(t)) 1900.
