8 File Name: 15.9.5.3-2.js
9 ECMA Section: 15.9.5.3-2 Date.prototype.valueOf
10 Description:
11
12 The valueOf function returns a number, which is this time value.
13
14 The valueOf function is not generic; it generates a runtime error if
15 its this value is not a Date object. Therefore it cannot be transferred
16 to other kinds of objects for use as a method.
