Hi guys, Based on the discussion about time management in https://github.com/apache/flink/pull/3641 , does it make sense to use nanoTime for procTime semantic aggregation processing? This way we will not have the possibility of events falling in the same "millisecond" processing bucket and keep a consistent aggregation sorting (also in the state). I understand that event-time cannot be managed in nanosecond as java does not give wall-clock time in nanoseconds, but for the procTime within the JVM we should be safe.
Please let me know what you think. Best, Stefano
