As I can see there is not a lot of modification to make the new attribute be able to convert a value to DateTime or DateTimeImmutable objects depends on the property type.

Could you make the new attribute to be able to do that?
I'd rename it ToDateTime or create a separate attribute.

PHP recommends use DateTimeImmutable by default. Is there a case for use mutable DateTime?

Despite on recommendations people still use mutable objects

I'd go with immutable and add mutable if/when requested.

@xepozz @samdark I added DateTime support, but used immutable object, if it avaliable.
