Description

The proto schema includes Timestamp and Duration with nano precision. The logical types should be promoted to the core logical types, so they can be handled on various IO's as standard mandatory conversions.

This means that the logical type should use the proto specific Timestamp and Duration but the java 8 Instant and Duration.
