SlowQueryListener always shows time as 0, QueryLoggingListener shows correct time.

It appears that while using the SlowQueryListener as shown below, the Time property in the logging is always 0. But the time appears to work correctly when using the QueryListener (without threshold specified, logs everything). I’ve run it a few times to ensure the query are not too quick and are genuinely being shown as 0. I feel like i’m missing something basic…

I’m testing against both H2 and MySQL via Hikari, JPA+Hibernate is actually executing the queries, full range of SELECTs, INSERTs, UPDATEs etc if that makes any difference. Using the latest versions of everything on Java 8 b121.
