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