michael@0:    ECMA Section:       15.9.5.34 Date.prototype.setMonth(mon [, date ] )
michael@0:    Description:
michael@0:    If date is not specified, this behaves as if date were specified with the
michael@0:    value getDate( ).
michael@0: 
michael@0:    1.  Let t be the result of LocalTime(this time value).
michael@0:    2.  Call ToNumber(date).
michael@0:    3.  If date is not specified, compute DateFromTime(t); otherwise, call ToNumber(date).
michael@0:    4.  Compute MakeDay(YearFromTime(t), Result(2), Result(3)).
michael@0:    5.  Compute UTC(MakeDate(Result(4), TimeWithinDay(t))).
michael@0:    6.  Set the [[Value]] property of the this value to TimeClip(Result(5)).
michael@0:    7.  Return the value of the [[Value]] property of the this value.
