Time & Frequency Services

The National Institute of Standards and Technology is responsible for maintaining and disseminating official time in the United States. While NIST does not have a direct role in implementing clock changes for daylight saving time, it does play an important role in ensuring that timekeeping systems across the country are accurate and consistent.

Prior to the implementation of daylight saving time, NIST issues public announcements reminding individuals and organizations to adjust their clocks accordingly. NIST also provides resources to help people synchronize their clocks, such as the time.gov website and the NIST radio station WWV.

In addition, NIST is responsible for developing and maintaining the atomic clocks that are used to define Coordinated Universal Time (UTC), the international standard for timekeeping. UTC is used as the basis for all civil time in the United States, and it is the reference time used by many systems, including the Global Positioning System (GPS) and the internet.

Overall, while NIST does not have a direct role in implementing clock changes for daylight saving time, it plays an important role in ensuring that timekeeping systems across the country are accurate and consistent, which is essential for the smooth implementation of any changes to the system.

…When we talk about standards in our personal lives, we might think about the quality we expect in things such as restaurants and first dates. But the standards that exist in science and technology have an even greater impact on our lives. Technical standards keep us safe, enable technology to advance, and help businesses succeed. They quietly make the modern world tick and prevent technological problems that you might not realize could even happen…”

Abstract: Numerous modern technologies are reliant on the low-phase noise and exquisite timing stability of microwave signals. Substantial progress has been made in the field of microwave photonics, whereby low-noise microwave signals are generated by the down-conversion of ultrastable optical references using a frequency comb^1,2,3. Such systems, however, are constructed with bulk or fibre optics and are difficult to further reduce in size and power consumption. In this work we address this challenge by leveraging advances in integrated photonics to demonstrate low-noise microwave generation via two-point optical frequency division^4,5. Narrow-linewidth self-injection-locked integrated lasers^6,7 are stabilized to a miniature Fabry–Pérot cavity⁸, and the frequency gap between the lasers is divided with an efficient dark soliton frequency comb⁹. The stabilized output of the microcomb is photodetected to produce a microwave signal at 20 GHz with phase noise of −96 dBc Hz⁻¹ at 100 Hz offset frequency that decreases to −135 dBc Hz⁻¹ at 10 kHz offset—values that are unprecedented for an integrated photonic system. All photonic components can be heterogeneously integrated on a single chip, providing a significant advance for the application of photonics to high-precision navigation, communication and timing systems.

Technical Barriers to Trade

World According to Marco Polo

We track action in international administrative procedures that affect the safety and sustainability agenda of the education facility industry. From time to time we find product purchasing contracts that contain “boilerplate” requiring conformity to applicable regulations found in the Agreement on Technical Barriers to Trade (TBT). Common examples are found in contracts for the acquisition of information technology and specialty laboratory equipment.

The World Trade Organization TBT Agreement obliges all Parties to maintain an inquiry point that is able to answer questions from interested parties and other WTO Members regarding technical regulations, standards developed by government bodies, and conformity assessment procedures, as well as provide relevant documents. The TBT Agreement also requires that WTO Members notify the WTO of proposed technical regulations and conformity assessment procedures so interested parties can become acquainted with them and have an opportunity to submit written comments.

Technical Barriers to Trade Information Management System

The inquiry point and notification authority for the United States is operated by the National Institute of Standards and Technology an agency within the U.S. Department of Commerce. We provide a link here for the convenience of faculty, specifiers and purchasing professionals.

Blockchain Technology

Distributed Ledger Technology

The U.S. Commerce Department’s National Institute of Standards and Technology (NIST) issued a draft report — and a commenting opportunity the repport — that details a high-level technical overview of blockchain technology, its architecture, and how it works as the foundation of modern cryptocurrencies. NIST requested feedback from the public and private sectors, national and international, for the final publication. The document, Draft NIST Interagency Report (NISTIR) 8202: Blockchain Technology Overview, provided an in-depth look at the technologies that compromise blockchain systems and breaks down how blockchains can best be utilized, and how blockchain technology can be an asset to a business and its products.

“We want to help people understand how blockchains work so that they can appropriately and usefully apply them to technology problems,” said Dylan Yaga, a NIST computer scientist and co-author of the report. “It’s an introduction to the things you should understand and think about if you want to use blockchain.”

The report appears to have integrated public comment and now a landing page for NIST work in this area — as well as contact information for project leaders — is linked below
