Je suis en train de lire des données de séries temporelles à partir de fichiers dans la trame de données R. Voir ci-dessous la colonne avec les dates. Je montre seulement pour l'année 2009 parce qu'ici j'obtiens un problème que je décris ci-dessous. il semble assez habituel jusqu'à ici.Répétition indésirable lors de l'ajout d'heures à l'objet POSIX

Comme je l'ai souligné dans la figure ci-dessous pour '2009-03-30' heure 00:00:00 répète deux fois. Ce n'est pas le cas avec d'autres dates. Seulement pour très peu de dates je vois une telle duplication. Toute raison que vous pouvez trouver ou vous avez besoin de plus d'informations, s'il vous plaît faites le moi savoir.
s'il vous plaît nous donner 'dput (données)' – etienne
dput encombrerait le poste. J'ai ajouté une image si cela est utile. – Jio
