  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.
