Hi! Recently Amazon announced launch of Amazon Time Sync Service (https://aws.amazon.com/blogs/aws/keeping-time-with-amazon-time-sync-service/) and now it's AWS-recommended way for time sync on EC2 instances (https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/set-time.html). It's stated there that chrony is faster / more precise than ntpd.
Nothing to say correct time sync configuration is very important for any C* setup. Does anybody have positive experience using crony, Amazon Time Sync Service with Cassandra and/or combination of them? Any concerns regarding chrony + Amazon Time Sync Service + Cassandra? Are there any chrony best-practices/custom settings for C* setups? Thanks, Kyrill
