Immutable date format (as DateTimeImmutable) are not supported

[jdecool]

I try to use the bundle on a project which is using DateTimeImmutable objects.

But the bundle not support it.

I start a PR #1941

I'm closing this issue because we're starting a new phase in the history of this bundle (see #2059). We've moved it into a new GitHub organization and we need to start from scratch: no past issues, no pending pull requests, etc.

I understand if you are angry or disappointed by this, but we really need to "reset" everything in order to reignite the development of this bundle.
