/**
   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.
