| 8 File Name: date-003.js | |
| 9 Corresponds To 15.9.5.3-1.js | |
| 10 ECMA Section: 15.9.5.3-1 Date.prototype.valueOf | |
| 11 Description: | |
| 12 | |
| 13 The valueOf function returns a number, which is this time value. | |
| 14 | |
| 15 The valueOf function is not generic; it generates a runtime error if | |
| 16 its this value is not a Date object. Therefore it cannot be transferred | |
| 17 to other kinds of objects for use as a method. | |
