From manual page: http://www.php.net/datetimeimmutable.modify

Regarding the definition of an Immutable object ( https://en.wikipedia.org/wiki/Immutable_object ), I guess letting user modify an immutable it's not something we are supposed to do.

From manual page:
>Creates a new DateTimeImmutable object with modified timestamp. The original object is not modified.

Maybe the name of the method is ambiguous, but it doesn't modify your object, it just create a new instance with the modification made.

Yes I agree with you, the name is too ambiguous.

Just closing this bug as it is the wrong package. It can't seem to be possible to change the category but just open a new issue (but afair there is already one about it) using the correct Date/Time category, not pecl's package.

As explained, this method doesn't actually modify the DateTimeImmutable instance and is just an artifact of DateTime and DateTimeImmutable having the same API.
