Amazon Time Sync Service adds support for Microsecond accurate time on 26 additional EC2 instance types in all commercial regions

Amazon Time Sync Service now supports microsecond accurate time on 26 additional EC2 instance types across all commercial regions. Built on AWS Nitro System infrastructure, this feature provides nanosecond precision hardware timestamps via Precision Time Protocol hardware clocks (PHC). Customers can access this capability by creating a Precision Time Placement Group (PTPG), a new placement strategy. For workloads requiring both low network latency and precision time, PTPGs can be associated with Cluster Placement Groups (CPGs), enabling distributed applications to order events, measure one-way network latency, and increase transaction speed.
