The table below lists the time servers used by the NIST Internet Time Service (ITS). The table lists each server's name, IP address, and location, organized geographically within the US from North to South …

Internet time servers use several standard timing protocols defined in a series of RFC (Request for Comments) documents. The three major timing protocols are the Time Protocol, the Daytime …

In addition to operating Internet and telephone-based time services, we also conduct research on improving the accuracy and efficiency of these services, and on developing ways to authenticate and …

The TMSS works by continuously monitoring the time offsets between the BSJ reference time and each connected customer’s clock as seen through its NTP server. Reports are generated regularly to help …

The load on the MST Internet time servers is increasing by 9% per month, and we have investigated methods that can be used to address this increasing demand without a corresponding increase in the …

Among the first six selections, there is no closer you are to the selected server, the more the time it takes for data to travel over the second) in the time setting.

This document explains methods by which computers running Windows 2000 or Windows XP can get the time from the National Institute of Standards and Technology (NIST), an accurate and official …

Instructions for using the NIST authenticated Network Time Protocol (NTP) server These instructions explain how to add symmetric-key authentication to the most common version of the NTP software.

Abstract The National Institute of Standards and Technology (NIST) operates 22 network time servers at various locations. These servers respond to requests for time in a number of different formats and …

The time of the servers is directly traceable to the UTC(NIST) time scale, which is maintained by an ensemble of atomic clocks and hydrogen masers located at the MST laboratory in Boulder, Colorado.
