La classe DateTimeImmutable

(PHP 5 >= 5.5.0, PHP 7, PHP 8)

Représentation d'une date et heure.

Cette classe se comporte de manière identique à DateTime à l'exception que de nouveaux objets sont retournés quand des méthodes de modification telle que DateTime::modify() sont appelées.

class DateTimeImmutable implements DateTimeInterface {
/* Constantes héritées */
public const string DateTimeInterface::ATOM = "Y-m-d\\TH:i:sP";
public const string DateTimeInterface::COOKIE = "l, d-M-Y H:i:s T";
