The new feature added with https://bugs.openjdk.org/browse/JDK-8298175 could be used by the NMT JFR events. Instead of using an external timestamp to get the same time in the events, the periodic timestamp could be used.
This would also get rid of the need for an interval to share the NMTUsage, if the same timestamp is used, the same usage should be used.
