Support boundary to configure the Windows Time service for high-accuracy environments


This article describes the support boundary to configure the Windows Time (W32Time) service for high-accuracy environments. High-accuracy environments include exchange trading houses and high-precision manufacturing companies for whose success critically accurate time measurement is required. Often, accuracy is measure as compared to UTC, and desired accuracies range from 1 sec to 1 millisecond. 

More Information

The W32Time service uses MS-NTP for domain communication and Network Time Protocol (NTP). MS-NTP is similar to Simple Network Time Protocol (SNTP) which is a simplified version of NTP.

SNTP is used in non-domain-joined computers. (This includes Windows Server-based computers.)

Windows XP and later versions of the Windows operating system implement NTP.

Under the right conditions you can maintain 1 ms accuracy with regard to UTC. With careful attention to your computer and network environment, and a solid time source which is accurate and reliable, you should be able to achieve 1 ms accuracy.

For more information and details, please see the Windows 2016 Accurate Time document on TechNet.
