| info: | |
| 1. Let t be ? thisTimeValue(this value). |
| 2. If t is NaN, let t be +0; otherwise, let t be LocalTime(t). |
| 3. Let y be ? ToNumber(year). |
| 4. If month is not specified, let m be MonthFromTime(t); otherwise, let m be |
| ? ToNumber(month). |
| 5. If date is not specified, let dt be DateFromTime(t); otherwise, let dt be |
| ? ToNumber(date). |
| 6. Let newDate be MakeDate(MakeDay(y, m, dt), TimeWithinDay(t)). |
| 7. Let u be TimeClip(UTC(newDate)). |
| 8. Set the [[DateValue]] internal slot of this Date object to u. |
| 9. Return u. |
