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

Amazon Time Sync Service Updates

Amazon Time Sync Service now supports microsecond accurate time on 26 additional EC2 instance types across all commercial regions. This enhancement, built on Amazon's network infrastructure and the AWS Nitro System, offers nanosecond precision hardware timestamps by leveraging reference clocks directly in the Nitro System. This enables customers to order application events, measure 1-way network latency, and boost distributed application transaction speed.

New Features

• Microsecond accurate time on 26 additional EC2 instance types.
• New Precision Time Placement Group (PTPG) for launching instances with Precision Time Protocol hardware clock (PHC) enabled.
• PTPG can be associated with Cluster Placement Group (CPG) for low-latency workloads.

What to do

• Create a Precision Time Placement Group (PTPG) to access microsecond accurate time.
• Associate PTPG with Cluster Placement Group (CPG) for low-latency workloads.
