PHP: DateTime - Manual
The DateTime class
(PHP 5 >= 5.2.0, PHP 7, PHP 8)
Introduction
Representation of date and time.
This class behaves the same as DateTimeImmutable, except objects are modified itself when modification methods such as DateTime::modify() are called.
Warning
Calling methods on objects of the class DateTime
will change the information encapsulated in these objects, if you want to
prevent that you will have to use clone operator to
create a new object. Use DateTimeImmutable
instead of DateTime to obtain this recommended
behaviour by default.
