[jira] [Commented] (CASSANDRA-15216) Cross node message creation times are disabled by default

    [ https://issues.apache.org/jira/browse/CASSANDRA-15216?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16920755#comment-16920755 ] 

Benedict commented on CASSANDRA-15216:
--------------------------------------

Thanks for the offer.  This is a two word change, though (from {{false}} to  {{true}}, in {{cassandra.yaml}} and {{Config}}), and probably too trivial to even bother with submission and review; it can probably be ninja'd in.  The only requirement is a brief discussion to confirm nobody disagrees this should happen.

> This can cause a lot of wasted work for messages that have timed out on the coordinator.  We should generally assume that our users have setup NTP on their clusters, and that clocks are modestly in sync, since it’s a requirement for general correctness of last write wins.
