8 ECMA Section: 15.9.5.3 Date.prototype.toDateString()
9 Description:
10 This function returns a string value. The contents of the string are
11 implementation dependent, but are intended to represent the "date"
12 portion of the Date in the current time zone in a convenient,
13 human-readable form. We can't test the content of the string,
14 but can verify that the string is parsable by Date.parse
16 The toDateString function is not generic; it generates a runtime error
17 if its 'this' value is not a Date object. Therefore it cannot be transferred
18 to other kinds of objects for use as a method.
