Describe the bug
DateTime scalar auto converts to UTC by design

See test that confirms this was intentional

To Reproduce
Steps to reproduce the behavior:
Use DateTime in a query

Expected behavior
The RFC 3339 spec doesn't mention anything about shifting to UTC, so it should keep all timezone adjustments

LocalDateTime isn't listed in the documentation as an available scalar.
