`periodlength`

Calcule la quantité d'unités temporelles entre deux dates.

L'une des unités de temps suivantes doit être spécifiée :

jours;
semaines;
moins ; et
années.

L'expression periodlength doit également indiquer si la date de fin de la période est inclusive ou exclusive ou la date de fin (la période est toujours inclusive de la date de début).

Le calcul de la période est toujours arrondi à l'entier le plus proche.
