1. Let y be ? ToNumber(year).
|
|
2. Let m be ? ToNumber(month).
|
|
3. If date is supplied, let dt be ? ToNumber(date); else let dt be 1.
|
|
4. If hours is supplied, let h be ? ToNumber(hours); else let h be 0.
|
|
5. If minutes is supplied, let min be ? ToNumber(minutes); else let min be 0.
|
|
6. If seconds is supplied, let s be ? ToNumber(seconds); else let s be 0.
|
|
7. If ms is supplied, let milli be ? ToNumber(ms); else let milli be 0.
|
|
8. If y is not NaN and 0 ≤ ToInteger(y) ≤ 99, let yr be 1900+ToInteger(y);
|
|
otherwise, let yr be y.
|
|
9. Return TimeClip(MakeDate(MakeDay(yr, m, dt), MakeTime(h, min, s, milli))).
