Problem:
The Camunda engine uses a custom date format (https://docs.camunda.org/manual/develop/reference/rest/overview/date-format/). If an OpenAPI client generator uses a date library incompatible with the Camunda custom date format, data validation will fail.

Expected:
As a user, I can read about the Camunda custom date format in the Camunda OpenAPI docs. This will help me understand that I need to check if the OpenAPI generator used supports the date format, or I need to adjust it.
