2010年2月10日 · NIST operates several stratum-1 network time servers, which means their time is directly linked to UTC (NIST), the official NIST time. Other sources of time are not monitored or certified by NIST. Here are the server names, locations, and IP addresses and current status.
Setting Your Computer Clock - NIST
2023年4月27日 · The service can be used to set computer clocks and other devices with several different time protocols, but the Network Time Protocol (NTP) is the most prevalent. The Automated Computer Time Service (ACTS) is used to synchronize computer clocks and other devices through analog phone lines.
What Time is It? FAQs - NIST
2024年9月16日 · The current time is shown on the Internet at https://www.time.gov/ - it synchronizes with NIST every ten minutes. There is an accuracy statement based on a measurement of the round-trip network delay. This delay is measured using your computer clock as a timer each time synchronization is made.
National Institute of Standards and Technology - NIST
The National Institute of Standards and Technology - Time and Frequency Division maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in …
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 Protocol, and the Network Time Protocol (NTP). The time servers are continually “listening” for timing requests sent using any of these three protocols. When

pool.ntp.org: NTP Servers in United States, us.pool.ntp.org
In most cases it's best to use pool.ntp.org to find an NTP server (or 0.pool.ntp.org, 1.pool.ntp.org, etc if you need multiple server names). The system will try finding the closest available servers for you.
NIST Internet Time Service | Commerce Data Hub
Distributes NIST estimate of official U.S. time over the Internet in real time, using Network Time Protocol (NTP) and other time data formats to automatically synchronize clocks in computers and network devices to official U.S. time as realized by NIST several billions of times per day.
NIST Time Widget
This widget is a public service provided by the Time and Frequency Division of the National Institute of Standards and Technology (NIST). It is a web clock showing the official time of day from NIST, displayed as a 12 or 24-hour clock, in a user-selectable time zone.
