Amazon Time Sync Service Updates

Amazon Time Sync Service now supports microsecond-accurate time on 135 additional EC2 instance types across 12 instance families in all commercial regions. This enhancement leverages Amazon's network infrastructure and the AWS Nitro System, providing nanosecond-precision hardware timestamps.

Newly Supported Instance Families

  • Gen8 families: C8a, C8i, C8i-flex, C8id, M8i, M8i-flex, R8a, X8i
  • Gen9 families: C9g, C9gd, M9g, M9gd

Precision Time Placement Group (PTPG)

Customers can now create a PTPG to launch instances with Precision Time Protocol hardware clock (PHC) enabled. This placement strategy allows for microsecond-accurate time and can be associated with a Cluster Placement Group (CPG) for low-latency workloads.

What to do

  • Create a PTPG to enable microsecond-accurate time on supported instance types.
  • Associate a PTPG with a CPG for low-latency, precision time benefits.
