   File Name:          date-001.js
   Corresponds To:     15.9.5.2-2.js
   ECMA Section:       15.9.5.2 Date.prototype.toString
   Description:
   This function returns a string value. The contents of the string are
   implementation dependent, but are intended to represent the Date in a
   convenient, human-readable form in the current time zone.

   The toString 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.


   This verifies that calling toString on an object that is not a string
   generates a runtime error.
