As the type of the first parameter is string, we can assign a relative date for it.

Example:



<?php

$immutable = new DateTimeImmutable('-1 year', new DateTimeZone('Asia/ShangHai'));

echo $immutable->format('Y-m-d H:i:s');

?>



It looks like the parameter of function strtotime and is very helpful for us to get an immutable relative DateTime object.
