You can now monitor the system time accuracy for your Amazon ECS tasks running on AWS Fargate. For time-sensitive workloads running on Fargate, this gives customers the ability to monitor the clock error bound, which is used as a proxy for clock error, to know if the difference between reference time and system time exceeds a threshold. This capability leverages Amazon Time Sync Service to measure clock accuracy and provide the clock error bound for containers.

The clock error bound information is available to query through the task metadata endpoint version 4 in all AWS Regions where AWS Fargate is available. To read more about clock accuracy and clock error bound, refer to this blog post.
