  24     ECMA Section:       15.9.5.5
  25     Description:        Date.prototype.getYear
  26
  27     This function is specified here for backwards compatibility only. The
  28     function getFullYear is much to be preferred for nearly all purposes,
  29     because it avoids the "year 2000 problem."
  30
  31         1.  Let t be this time value.
  32     2.  If t is NaN, return NaN.
  33     3.  Return YearFromTime(LocalTime(t)) 1900.
