Yes, this is kind a trend of supporting precision time on cloud instance. Check this [It’s About Time: Microsecond-Accurate Clocks on Amazon EC2 Instances](https://aws.amazon.com/blogs/compute/its-about-time-microsecond-accurate-clocks-on-amazon-ec2-instances/) from AWS.

@godunkchen can you double-check that URL? I’m getting a 404.

Sorry about that. I’ve fixed it.

Here is the announcement [Amazon Time Sync Service now supports Nanosecond Hardware Packet Timestamps](https://aws.amazon.com/about-aws/whats-new/2025/06/amazon-time-sync-nanosecond-hardware-packet-timestamps/) about nanosecond precision.
