1.6 Ensure clocks are synchronized on all nodes

Information

Enabling Network Time Protocol (NTP), or some equivalent way, to keep clocks on all nodes in sync is critical.

Rationale:
Cassandra decides which data is most current between all of the nodes in the cluster based on timestamps. It is paramount to ensure all clocks are in-sync, otherwise the most current data may not be returned or worse, marked for deletion.

Solution

Install and start the time protocol on every node in the Cassandra cluster.
