The Standard Time and Frequency Signal (STFS) is a time signal service available in the United States which provides standard time and frequency signals, broadcast on very precise carrier frequencies by the U.S. Naval Observatory and the National Institute of Standards and Technology (NIST), formerly the National Bureau of Standards (NBS).
A similar service is operated in the United Kingdom by the National Physical Laboratory, broadcasting from Anthorn radio station in north-west England, and by the BBC using the 198kHz carrier of the Radio 4 national radio station with a frequency accuracy of 1 part in 1011.
The National Physical Laboratory, India is the premier research laboratory in India in the field of physical sciences. NPLI continues to disseminate standard time and frequency signals (STFS) via geostationary satellite INSAT with an accuracy of 10 ms.
Famous quotes containing the words standard, time, frequency, signal and/or service:
“Any honest examination of the national life proves how far we are from the standard of human freedom with which we began. The recovery of this standard demands of everyone who loves this country a hard look at himself, for the greatest achievments must begin somewhere, and they always begin with the person. If we are not capable of this examination, we may yet become one of the most distinguished and monumental failures in the history of nations.”
—James Baldwin (1924–1987)
“The chuck wagon carries the food and utensils for the range kitchen. Man-at-the-pot is the first buckaroo to pick up the coffee pot when out with the chuck wagons. It becomes his duty to pour the coffee for the outfit. “Come and get her before I throw her out” is the time honored mess call.”
—Administration in the State of Neva, U.S. public relief program (1935-1943)
“The frequency of personal questions grows in direct proportion to your increasing girth. . . . No one would ask a man such a personally invasive question as “Is your wife having natural childbirth or is she planning to be knocked out?” But someone might ask that of you. No matter how much you wish for privacy, your pregnancy is a public event to which everyone feels invited.”
—Jean Marzollo (20th century)
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“The true courage of civilized nations is readiness for sacrifice in the service of the state, so that the individual counts as only one amongst many. The important thing here is not personal mettle but aligning oneself with the universal.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
