Dauer berechnen

Eventuell müssen Sie Benutzern häufig eine Möglichkeit geben, anzugeben, wann eine Aufgabe oder ein Prozess fällig ist. Mit der DurationCalculator-Skripteinbindung können Sie das Fälligkeitsdatum entweder als einfache Dauer oder als relative Dauer berechnen.

Normalerweise erfordert das Festlegen eines Fälligkeitsdatums die Berechnung der Arbeitszeit und nicht der Gesamtzeit. Nur der Teil des Tages, an dem gearbeitet wird, wird bei der Bestimmung des Fälligkeitsdatums berücksichtigt. Zum Beispiel ist eine Aufgabe in 10 Stunden fällig, aber auf einen Geschäftstagzeitplan beschränkt. Wenn die Arbeit am Montag um 10 Uhr beginnt, ist sie wie unten berechnet am Dienstag um 12 Uhr fällig.

10am-5pm on Monday (6 hours) + 8am-12pm on Tuesday (4 hours)

Informationen zu Zeitplänen, die Sie als Eingaben für DurationCalculator-Methoden verwenden können, finden Sie unter Zeitpläne erstellen und verwenden.

Dieses Skript veranschaulicht die Verwendung von DurationCalculator zur Berechnung eines Fälligkeitsdatums.
