+   File Name:          15.9.5.3.js
+   ECMA Section: 15.9.5.3 Date.prototype.toDateString()
+   Description:
+   This function returns a string value. The contents of the string are
+   implementation dependent, but are intended to represent the "date"
+   portion of the Date in the current time zone in a convenient,
+   human-readable form.   We can't test the content of the string, 
+   but can verify that the string is parsable by Date.parse
+
+   The toDateString 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.
