Amazon Time Sync is now available over the internet as a public NTP service
The Amazon Time Sync Service is now available over the Internet. Built on Amazon's network infrastructure, the Amazon Time Sync Service utilizes a global fleet of redundant satellite-connected and atomic reference clocks in AWS regions to deliver current time readings of the Coordinated Universal Time (UTC) global standard. Previously, Amazon Time Sync was available through EC2 instances.

Now, you can access the Amazon Time Sync Service at time.aws.com as a publicly available NTP service in addition to the connection provided directly to EC2 instances. This means your devices and infrastructure outside of AWS, such as IOT devices and on-premises infrastructure, can synchronize to the same highly available time sources that were previously accessible only from within our data centers. In the event of a leap second, the Amazon Time Sync service automatically handles this for you by smoothing out the addition, or removal, of the leap second with a 24-hour linear smear from noon to noon UTC.
To get started, see the userguide on adding time.aws.com to your NTP client.
Amazon Time Sync NTP Pools are available in all public AWS Regions, AWS GovCloud (US) Regions, and worldwide over the internet. To learn more about Amazon Time Sync Service, see the EC2 User guide.
