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.
