             Summary: Show time drift between nodes when using nodetool ring
                 Key: CASSANDRA-4680
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4680
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Patrick McFadin
            Priority: Minor


>From the docs:
Server clock synchronization is more important in 1.2; replicas
will use a coordinator-provided timestamp to determine when a
request has timed out and is thus not worth proceeding with.
Using a service like NTP is strongly recommended.

Since this is now more important than ever, my proposed enhancement would be to 
the nodetool command. When displaying the "ring" information, add the time 
drift as relative to the current host.

This would be a valuable tool to aid in diagnostics.
