   File Name:          15.9.5.37-1.js
   ECMA Section:       15.9.5.37 Date.prototype.setUTCFullYear(year [, mon [, date ]] )
   Description:

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

   1.   Let t be 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 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.
