Клас DateTime

(PHP 5 >= 5.2.0, PHP 7, PHP 8)

Вступ

Представлення дати й часу.

This class behaves the same as DateTimeImmutable, except objects are modified itself when modification methods such as DateTime::modify() are called.

Увага

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.

7.2.0	The class constants of DateTime are now defined on DateTimeInterface.
7.1.0	The DateTime constructor now includes the current microseconds in the constructed value. Before this, it would always initialise the microseconds to `0`.
