| michael@0 | 8 | ECMA Section: 15.9.5.3 Date.prototype.toDateString() |
| michael@0 | 9 | Description: |
| michael@0 | 10 | This function returns a string value. The contents of the string are |
| michael@0 | 11 | implementation dependent, but are intended to represent the "date" |
| michael@0 | 12 | portion of the Date in the current time zone in a convenient, |
| michael@0 | 13 | human-readable form. We can't test the content of the string, |
| michael@0 | 14 | but can verify that the string is parsable by Date.parse |
| michael@0 | 15 | |
| michael@0 | 16 | The toDateString function is not generic; it generates a runtime error |
| michael@0 | 17 | if its 'this' value is not a Date object. Therefore it cannot be transferred |
| michael@0 | 18 | to other kinds of objects for use as a method. |
