   File Name:          15.9.5.36-1.js
   ECMA Section:       15.9.5.36 Date.prototype.setFullYear(year [, mon [, date ]] )
   Description:

   If mon is not specified, this behaves as if mon were specified with the
   value getMonth( ). If date is not specified, this behaves as if date were
   specified with the value getDate( ).

   1.   Let t be the result of LocalTime(this time value); but if this time
   value is NaN, let t be +0.
   2.   Call ToNumber(year).
   3.   If mon is not specified, compute MonthFromTime(t); otherwise, call
   ToNumber(mon).
   4.   If date is not specified, compute DateFromTime(t); otherwise, call
   ToNumber(date).
   5.   Compute MakeDay(Result(2), Result(3), Result(4)).
   6.   Compute UTC(MakeDate(Result(5), TimeWithinDay(t))).
   7.   Set the [[Value]] property of the this value to TimeClip(Result(6)).
   8.   Return the value of the [[Value]] property of the this value.
