/**
File Name: 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.
