| Behavior when the "this" value is a Date object describing an invald date |
| info: | |
| 1. Let t be LocalTime(? thisTimeValue(this value)). |
| 2. Let h be ? ToNumber(hour). |
| 3. If min is not specified, let m be MinFromTime(t); otherwise, let m be ? |
| ToNumber(min). |
| 4. If sec is not specified, let s be SecFromTime(t); otherwise, let s be ? |
| ToNumber(sec). |
| 5. If ms is not specified, let milli be msFromTime(t); otherwise, let milli |
| be ? ToNumber(ms). |
| 6. Let date be MakeDate(Day(t), MakeTime(h, m, s, milli)). |
| 7. Let u be TimeClip(UTC(date)). |
| 8. Set the [[DateValue]] internal slot of this Date object to u. |
| 9. Return u. |
