La classe DateTimeImmutable

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

Introduction

Représentation d'une date et heure.

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