    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.
