UTC is not an acronym. It's a madeup identifier that matches neither the English (Coordinated Universal Time) or the French (T U C.. I won't even attempt to figure out what it is..). Hi All, In fact, UTC is an acronym (already anticipated by Frnak and explicitly stated every minute). It is but one of several, this one being rather genericized (because any longer would force a lot of talking, and minute passes by pretty quickly). The others would include: UTC(NIST), UT1; and the academic UT0, and UT2. Au contraire... while UT1, UT0, and UT2 are, in fact, acronyms of a sort, primarily based on astronomical time, this is not the case for UTC.. the coordination has to do with matching up UT and TAI (atomic) time.. all those leap seconds, etc. As one online source puts it: The (Bureau Internationale de l'Heure) BIH was charged with the task of monitoring and maintaining the program and introduced the term Temps Universel Coordinné or Coordinated Universal Time for the coordinated time scale in 1964. BIH is the predecessor of the current BIPM (who seem to have a problem with the standard kilo losing mass) http://www.bipm.org/ or, for more information: http://syrte.obspm.fr/journees2004/PDF/Arias2.pdf which says: The name of Coordinated Universal Time UTC appeared in CCIR documents in the early 60s. One might also seek a paper from 1964, by Guinot. (who was a time guy at the BIH back then) A paper by Dennis McCarthy at USNO on "Evolution of Time Scales" mentions in Section 6 that: the term "Coordinated Universal Time" was introduced in the 1950s to designate a time scale in which the adjustments to quartz crystal clocks were coordinated among participating laboratories in the US and UK. A more recent paper by Guinot says: "Until 1965, the more or less common scale for emission of signals, which had received spontaneously the name of Coordinated Universal Time (UTC), had not been strictly defined." The reason for the initials order is that there is an hidden comma. Universal Time, Coordinated. Funny, thing, though, that if one searches the literature of the time for that particular sequence of words, it never occurs.. Given that Coordinated Universal Time existed well before UTC, I suspect that the comma thing is a post hoc creation. Wikipedia reports this as an erroneous expansion, but Wikipedia wasn't there in my Metrology classes (a couple dozen miles from NBS) where we worked with these NBS standards. It wasn't there when (1974) I performed the second leap second on my Cesium Beam Standard which was calibrated through WWVB (taking about half an hour, part of which was waiting during the roughly 15 minute intervals between TOCs). My antenna was so far away (on the fantail of the ship in another "time zone"), that I had to slip the time by 100nS. |

No comma is implied or needed because in French, an adjective follows the word it modifies, with very few exceptions. Roy Lewallen, W7EL |

Roy Lewallen, W7EL Roy, I think that as others have posted, it is neither English nor French, but a *******isation that doesn't concede either language to be the better for expressing the meaning. The diplomacy aspect of striking standards no doubt! Owen |

Funny, thing, though, that if one searches the literature of the time for that particular sequence of words, it never occurs.. You are writing to one who read the literature - at that time. My experience is not from arm chair history 101. UTC was arrived at as a compromise between the French (naturally) and the "rest of the world" (what else?). My bona fides are documented too: two diplomas from the only Metrology school in the United States - at that time. Time in service: with training in calibration and maintenance of the HP Cesium Beam standard, and VLF subsystem - at that time. I also lived through the great switch-over from cycles to hertz, and GMT to Zulu - at that time (or slightly before... I wasn't looking at the clock that day). I can flood this page with 250 references that employ the strict usage of "Universal Time Coordinated" "Universal Time, Coordinated" or "Universal Time (Coordinated)" and specifically 35 of them printed before 1967. With google it takes more time to cut and paste than actually find them. A short list includes: Title 15 1971 Code of Federal Regulations By United States Office of the Federal Register (1971) "... the Universal Time Coordinated (UTC) system' as recommended by the Bureau International de l'Heure (bill). The carrier offset currently is minus 300 ..." Meteorological and Geoastrophysical Abstracts By American Meteorological Society (1960) International Aerospace Abstracts By American Institute of Aeronautics and Astronautics Technical Information Service, United States National Aeronautics and Space Administration, Institute of the Aerospace Sciences Technical Information Service (1961) Proceedings of the IEEE. By Institute of Electrical and Electronics Engineers (1963) Scientific and Technical Aerospace Reports By United States. National Aeronautics and Space Administration. Scientific and Technical Information Division, United States National Aeronautics and Space Administration.

With google it takes more time to cut and paste than actually find them. A short list includes: I defer to your googling skills.. I tried the search above, turned up nothing (other than obvious derivative works like the wikipedia entry) in the first 10 pages of hits, and took the references from BIH as definitive. (I also tried WebOfScience, etc.) I also didn't trust references from post, say, 1970, because by then, you'd have seen definitions created by "back-formation" (i.e. finding words that match the acronym.. which, when it comes right down to it, is how lots of acronyms get created in the first place) Proceedings of the IEEE. By Institute of Electrical and Electronics Engineers (1963) Looked for this one, and couldn't find it. Which month? The oldest paper in Proceedings that has the term "universal time" in it is Hudson's paper in June 1967, p815 ff It refers to CCIR recommendation 374.1 and CCIR reports 365 (in 1965) and 366 in connection with the discussion of UTC and SAT, but doesn't actually define UTC, nor does it provide a reference to a defining source. (other than a "in press" paper by Cord and Hudson, "Some trends in UT") Smith's paper in the Proceedings in May 1972, seems to provide a fairly definitive history (page 481) citing the CCIR Study Group 7 Interim meeting in 1962 and CCIR Xth Plenary Assembly in 1963 (Vol III, p193), as well as an earlier recommendation of the IAU XIth General Assembly in 1961 ("Resolutions adopted by comm. 31" Trans IAU, Vol XI B(1961), p 329) Familiar with any service acronyms like BFD? Sure.. but this is really a Tiny FD.. But, I really would like to find a definitive printed reference, as opposed to the recollections of folks present at the birth. Think of it as something akin to the citations in the OED. Once you have that golden reference, discussions like this one end in a hurry. It's also because I'm casually interested in the obscure history of things like this. A co-worker asked the other day, "Why is wine in 750ml bottles, and when did it change from whatever they used before the metric system existed?"... turns out it's actually a fairly recent change. Another interesting discussion had to do with the use of "transfer standards" when building the pyramids in Egypt: failure to calibrate your working cubit against the standard within the calibration interval was punishable by death. No "For indication only, out of cal" stickers there, apparently. {I'm also looking for a definitive source for that story...presumably it would be in hieroglypics.. as one can imagine, though, there's a lot of very odd stuff out there when you bring up anything ancient Egypt related) Jim, W6RMK |
