[jira] [Created] (CASSANDRA-6680) Clock skew detection via gossip

Brandon Williams created CASSANDRA-6680:
-------------------------------------------

             Summary: Clock skew detection via gossip
                 Key: CASSANDRA-6680
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-6680
             Project: Cassandra
          Issue Type: New Feature
          Components: Core
            Reporter: Brandon Williams
            Assignee: Brandon Williams
            Priority: Minor
             Fix For: 3.0


Gossip's HeartbeatState keeps the generation (local timestamp the node was started) and version (monotonically increasing per gossip interval) which could be used to roughly calculate the node's current time, enabling detection of gossip messages too far in the future for the clocks to be synced.
