/** File Name: date-003.js Corresponds To 15.9.5.3-1.js 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.
