> The local timestamp logical types could be added to the interop tests, to verify that the values roundtrip correctly between languages. These tests would then have to be run in an environment where the local time is not UTC, to detect if one language uses UTC for conversions and another uses local time. I think this is a great idea, but what is the process for adding to the interop test schema? IIUC, it would affect many implementations at once. IMO, we should probably have the logical types entirely covered in the interop tests, eventually. -Mike
