   File Name:          15.9.5.30-1.js
   ECMA Section:       15.9.5.30 Date.prototype.setHours(hour [, min [, sec [, ms ]]] )
   Description:
   If min is not specified, this behaves as if min were specified with the
   value getMinutes( ). If sec is not specified, this behaves as if sec were
   specified with the value getSeconds ( ). If ms is not specified, this
   behaves as if ms were specified with the value getMilliseconds( ).

   1.  Let t be the result of LocalTime(this time value).
   2.  Call ToNumber(hour).
   3.  If min is not specified, compute MinFromTime(t); otherwise, call
   ToNumber(min).
   4.  If sec is not specified, compute SecFromTime(t); otherwise, call
   ToNumber(sec).
   5.  If ms is not specified, compute msFromTime(t); otherwise, call
   ToNumber(ms).
   6.  Compute MakeTime(Result(2), Result(3), Result(4), Result(5)).
   7.  Compute UTC(MakeDate(Day(t), Result(6))).
   8.  Set the [[Value]] property of the this value to TimeClip(Result(7)).
   9.  Return the value of the [[Value]] property of the this value.
