J'ai trouvé un script sur le net que j'ai dû un peu modifier pour les besoins. Ce script prend une date, regarde sa validité et la renvoit soit au format EU ou US (très intéressant pour plus tard !).
J'aimerai compliquer un peu plus en m'assurant que cette date se trouve bien aujourd'hui au plus tard ... c'est pour un test et je vois mal que l'on donne les résultat aujourd'hui hors qu'il est fait demain !
Voici mon script de base:
