----------------------------------------

             Summary: Failure Detector should log or ignore sudden time change to the past
                 Key: CASSANDRA-4925
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-4925
             Project: Cassandra
          Issue Type: Bug
          Components: Core
            Reporter: sankalp kohli
            Priority: Minor


If a machine goes back in time all of a sudden because of a problem, Gossip will insert a negative interArrivalTime. 
This will decrease the mean value and can cause this machine to mark other nodes as down and then mark them up as time passed. 
But we should log such occurrences.
