[time-nuts] Amazon AWS time sync service

[Vlad]

Hello Folks !

Some time ago Amazon AWS has introduced "Time Sync Service"
https://aws.amazon.com/about-aws/whats-new/2017/11/introducing-the-amazon-time-sync-service/

Looks like it is just some NTPD (based on chrony). I am wandering how to 
measure drift between of AWS regions (internal clocks on EC2 instances). 
And how accurate that NTPD itself. Any ideas ?

Regards,
Vlad
