    ECMA Section:       15.9.5.3-1 Date.prototype.valueOf
    Description:

    The valueOf function returns a number, which is this time value.

    The valueOf function is not generic; it generates a runtime error if
    its this value is not a Date object.  Therefore it cannot be transferred
    to other kinds of objects for use as a method.
