Bonjour

Voila, je voudrais savoir si je peut modifier le temps de vote, les votes sont programmées A 24 heures (dons sa fais que je peut voter qu'une seule foi par jour), je souhaiterais les mettre à 2 heures,
mon petit souci c'est que je vote qu'une Seul foi par jour, je voudrais savoir si je peut le remettre toutes les 2 heures, (les votes me servent pour des classements sur des site d'annuaire) code ci-joint des en php .
