Microsoft ended support for Windows Server 2003 on July 14, 2015. This change has affected your software updates and security options. Learn what this means for you and how to stay protected.

INTRODUCTION
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.
