  3. If NewTarget is not undefined, then

    a. Let y be ? ToNumber(year).

    b. Let m be ? ToNumber(month).

    c. If date is supplied, let dt be ? ToNumber(date); else let dt be 1.

    d. If hours is supplied, let h be ? ToNumber(hours); else let h be 0.

    e. If minutes is supplied, let min be ? ToNumber(minutes); else let min be 0.

    f. If seconds is supplied, let s be ? ToNumber(seconds); else let s be 0.

    g. If ms is supplied, let milli be ? ToNumber(ms); else let milli be 0.

    h. If y is not NaN and 0 ≤ ToInteger(y) ≤ 99, let yr be 1900+ToInteger(y); otherwise,

      let yr be y.

    i. Let finalDate be MakeDate(MakeDay(yr, m, dt), MakeTime(h, min, s, milli)).

    j. Let O be ? OrdinaryCreateFromConstructor(NewTarget, "%DatePrototype%", « [[DateValue]] »).

    k. Set O.[[DateValue]] to TimeClip(UTC(finalDate)).

    l. Return O.
