Ce programme trace une horloge indiquant l’heure. Utilisation: taper horloge(9,30,120) si vous voulez voir l’heure défiler pendant 2 minutes (120 s) à partir de 9h30. Taper horloge(9,30) simplement pour voir cette heure (9h30) s’afficher. L’étalonnage peut être amélioré (modifier le range de la fonction temporise) si on cherche une meilleure précision.
