/**
   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.
