michael@0:    ECMA Section:       15.9.5.3-1 Date.prototype.valueOf
michael@0:    Description:
michael@0: 
michael@0:    The valueOf function returns a number, which is this time value.
michael@0: 
michael@0:    The valueOf function is not generic; it generates a runtime error if
michael@0:    its this value is not a Date object.  Therefore it cannot be transferred
michael@0:    to other kinds of objects for use as a method.
