  • NIST Internet Time Service
    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 and then from East to West Please note that while we make every effort to ensure that the names of the servers are correct, we control the names of only the nist gov servers If you have
  • Configuring Windows 2000 and Windows XP to use NIST Time Servers
    Section 1: Purpose This document provides step-by-step instructions on how to use the NIST Internet Time Service (ITS) for computers running the Windows 2000 or Windows XP operating systems These operating systems have a built-in capability to use the NIST time servers to set and maintain the correct time on their computers’ time-of-day clock
  • instructions - NIST
    NIST disseminates the time using several methods short-wave and long-wave Two radio services are offered of They allow you to set your computer’s clock attached, NIST telephone provides dial-in a
  • A comparison of NTP servers connected to the same reference . . . - NIST
    The results of these comparisons reveal the time differences between the servers and UTC(NIST), the relative time differences between the servers (obtained in common-view mode), and the time stability of each server
  • Configuring Apple Macintoshes to use NIST Time Servers
    Section 1: Purpose This document provides step-by-step instructions for configuring Apple Macintosh computers to use the NIST Internet Time Service (ITS) Mac OS versions 8 5 and later have the built-in capability to use the NIST time servers to maintain the correct time on the Macintosh time-of-day clock
  • Computer Time Synchronization - NIST
    4 Computer Time Synchronization NIST operates a Internet Time Service from Boulder, Colorado using multiple servers distributed around the country The NIST servers distribute time using the Time, Daytime, and NTP formats and currently handle many millions of timing requests per day For a current list of IP addresses for the NIST servers and sample client software (Daytime Protocol) that you
  • Microsoft Word - ntp-authenticate-instructions. doc - NIST
    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
  • Practical Limitations of NTP Time Transfer - NIST
    The server clock was a rubidium oscillator that was disciplined to signals from the Global Positioning System (GPS) satellites via a 12-channel L1 band receiver, with an antenna mounted outdoors on the roof The accuracy of this clock was measured at NIST and found to be within 100 ns of Coordinated Universal Time (UTC)
  • Usage Analysis of the NIST Internet Time Service
    The Internet Time Service (ITS) at the National Institute of Standards and Technology (NIST) currently receives over 16 billion time requests per day ITS servers derive their system time from the NIST atomic-referenced time scale and distribute it freely to the public Here we explore ITS usage patterns discovered by analysis of inbound network traffic For example, over a period of four
  • Outline for SP 250-X - NIST
    The server software consists of the operating system; the software developed at NIST that handles time requests and steers the clock oscillator, and utilities used for file transfer and diagnostics
