description: Order of coercion of provided argument vs NaN check
info: |
  1. Let t be ? thisTimeValue(this value).
  2. Let dt be ? ToNumber(date).
  3. If t is NaN, return NaN.
  4. Let newDate be MakeDate(MakeDay(YearFromTime(t), MonthFromTime(t), dt), TimeWithinDay(t)).
  5. Let v be TimeClip(newDate).
  6. Set the [[DateValue]] internal slot of this Date object to v.
  7. Return v.
