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:
“I don’t have any problem with a reporter or a news person who says the President is uninformed on this issue or that issue. I don’t think any of us would challenge that. I do have a problem with the singular focus on this, as if that’s the only standard by which we ought to judge a president. What we learned in the last administration was how little having an encyclopedic grasp of all the facts has to do with governing.”
—David R. Gergen (b. 1942)
“O time that cut’st down all!
And scarce leav’st here
Memoriall
Of any men that were.”
—Robert Herrick (1591–1674)
“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 gods’ service is tolerable, man’s intolerable.”
—Plato (c. 427–347 B.C.)
