| 7 File Name: 15.9.5.3.js | |
| 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 | |
| 15 | |
| 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. | |
