| 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. |
