Describe the bug
The OpenAPI schemas do not match the responses from the API's themselves. They seem to differ in at least two ways:

1. Missing root element
   Each API response includes the serialized type name which is omitted from the declared schema
2. Incorrect date-time formatting
   API responses declare date-time fields, which are defined in OpenAPI3 to be compliant with RFC3339 §5.6 (ISO8601 style strings). API Endpoints are actually returning an object with a ticks field.

To Reproduce
Call /api/openapi.json to get schema
Call /api/users/current to get actual.

Expected behavior
Schema and actual should match

Actual behavior
Schema and actual do not match
