> 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.
