1.10 + File Name: 15.9.5.3.js
1.11 + ECMA Section: 15.9.5.3 Date.prototype.toDateString()
1.12 + Description:
1.13 + This function returns a string value. The contents of the string are
1.14 + implementation dependent, but are intended to represent the "date"
1.15 + portion of the Date in the current time zone in a convenient,
1.16 + human-readable form. We can't test the content of the string,
1.17 + but can verify that the string is parsable by Date.parse
1.18 +
1.19 + The toDateString function is not generic; it generates a runtime error
1.20 + if its 'this' value is not a Date object. Therefore it cannot be transferred
1.21 + to other kinds of objects for use as a method.
