23    File Name:          15.9.5.3-2.js
24    ECMA Section:       15.9.5.3-2 Date.prototype.valueOf
25    Description:
26
27    The valueOf function returns a number, which is this time value.
28
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.
