Problème génération d'une séquence de date

Version imprimable

Bonjour,

J'essaye de générer une séquence de date par pas de 5 minutes. La génération fonctionne très bien sauf qu'elle n'est pas complète. Pour être plus clair voici le code :

Code:

1
2
3
4
date_debut = "2009-03-29 00:00:00 PMT"
date_fin = "2009-03-30 00:00:00 PMT"
jour=seq(as.POSIXlt(date_debut),as.POSIXlt(date_fin),300)
jour=format(jour, "%m/%d/%y %H:%M:%S")

et j'obtiens le résultat suivant :

Code:

1

A première vu la génération a parfaitement fonctionné, mais si on regarde de plus prêt il y a une erreur. On passe de "03/29/09 01:55:00" à "03/29/09 03:00:00". Où sont passés les date entre ces intervalles ?

Impossible de savoir pourquoi. Si vous avez une explication, je vous remercie d'avance.

Votre probleme ne vient pas de votre code.

Merci de l'avoir tester.

C'est tout de même bizarre. Je viens de le retester sur mon ordinateur et sur celui d'une collègue et nous obtenu toutes les deux un vecteur de taille 277. Il me manque toujours les données entre "03/29/09 01:55:00" et "03/29/09 03:00:00".

Pourriez vous me dire quelle configuration et quelle version de R vous utilisez ?
Pour ma part je travaille sous Windows Vista (Windows 7 pour ma collègue) avec la version 2.11.0 (2.10.1 pour ma collègue).

J'arrive à contourner ce problème en rajoutant manuellement les données qui me manquent mais j'aimerais tout de même comprendre cette erreur.

Merci d'avance.

Apparemment cette erreur serait du au changement d'heure. Merci quand même d'avoir regarder.
