| 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))). |
