Coordinated Universal Time was a good articles nominee, but did not meet the good article criteria at the time. There may be suggestions below for improving the article. Once these issues have been addressed, the article can be renominated. Editors may also seek a reassessment of the decision if they believe there was a mistake. | ||||||||||

The Future section reeks of non-objective content. For instance, it is claimed that the proposed 2001 change is "drastic". I'm sure someone will argue that a yotto-second difference is "huge", but no reasonable person would find 6-7 hrs over 2600 years to be "drastic", imho. Worse yet, the 2022 *agreement* to eliminate the leap-second "by 2035" is completely missing!! Is this the "same" as the non-conference of 2023 that was cited? (several times.) Who ever is editing this either needs to do their due duty or step aside. By the way, I understand some of the issues involved in the loosening the coupling of atomic to orbital times (is there enough discussion here about the difference between the (fictitious) point through which the Earth passes to start another year and the (fictitious) point at which (supposedly) all points on the Earth (tectonics aside) "match" their cosmological orientation of previous year? Just a digression.) but it would be useful to understand or at least see a discussion about WHY people don't want the change AND why people DO want the change - both politically and technically. That's sorely lacking -it's called being objective. 71.30.94.234 ( talk) 22:00, 25 October 2023 (UTC)
The article states that English speakers originally proposed CUT, while French speakers proposed TUC. The compromise that emerged was UTC
But what about German and Danish people? Why were they not asked? Why only English and French?

The ITU felt it was best to designate a single abbreviation for use in all languages in order to minimize confusion. For example, in English the abbreviation for coordinated universal time would be CUT, while in French the abbreviation for "temps universel coordonné" would be TUC. To avoid appearing to favor any particular language, the abbreviation UTC was selected.
On 7 February 2024 @ Daniel Quinlan: modified a sentence in the lead to read
It is the effective successor to Greenwich Mean Time (GMT), although GMT remains in use in some contexts, alongside other regional and industry-specific time standards.
I request a word-by-word justification for this change, and that any passages that support it in the main body of the article be identified.
My issues with the sentence are (some emphasis added):
the effectiveaside for the moment, I suggest something like:
I'll be back later with more on UTC being the effective successor to GMT. A bit more detail on the replacement of GMT with UTC would also be good for the history section. Daniel Quinlan ( talk) 19:47, 7 February 2024 (UTC)It is the effective successor to Greenwich Mean Time (GMT), complemented by specialized time standards such as UT1 and TAI that are vital in science, navigation, and timekeeping.
I don't know whether this rephrasing helps alleviate the original concern so I will still come back with more on the "the effective" assertion later today. Daniel Quinlan ( talk) 22:55, 7 February 2024 (UTC)It is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. However, in specialized domains such as scientific research, navigation, and timekeeping, other standards like UT1 and TAI play a vital role.
The pips are no longer broadcast from Greenwich, but from the National Physical Laboratory in Teddington, Surrey, which uses Coordinated Universal Time (UTC) - the successor of GMT - for its reading.
The primary time standard by which the world regulates clocks and time is UTC. It is a 24-h time standard that uses highly precise atomic clocks combined with the Earth's rotation. Timing centers around the globe agreed to keep their time scales synchronized or coordinate and hence, the name coordinated universal time. It is the successor of Greenwich Mean Time (GMT). The UTC was defined by the International Radio Consultative Committee (CCIR), a predecessor organization of the ITU-TS, and is maintained by the Bureau International des Poids et Measures (BIPM).
UTC is the successor of Greenwich Mean Time (GMT) and is sometimes still called GMT.
...(UTC). This global standard, the successor to Greenwich Mean Time, steers the world's clocks and silently regulates our lives.
UTC is the successor to Greenwich Mean Time (GMT) and represents the primary time standard by which the world regulates clocks and time.
There, the International Bureau of Weights and Measures (BIPM) collects and averages time to produce International Atomic Time, which gives us Coordinated Universal Time. UTC, as its known, is the time; the global standard and successor to Greenwich Mean Time. If you want to know the real time in real time go to BIPM.org, and check the UTC master clock.
...heard all over Europe broadcasting Coordinated Universal Time (UTC, the successor to Greenwich Mean Time or GMT) in Morse Code.
...UTC (Coordinated Universal Time after a French fudge; it is the successor to Greenwich Mean Time (GMT) or 'Zulu').
The U.S. victory would in turn officially and finally spell the end of the last vestige of empire for the United Kingdom, which still retains its beloved GMT as the official time standard even as most of the world has anointed UTC. Until now the distinction between the two has been merely semantic, because the two standards have remained linked by the leap second. But GMT is by definition based on earth time. If the leap second disappears and official time diverges from earth time, GMT will be a relic, an historical curiosity--like the Greenwich Observatory itself, which is now a privately owned museum rather than a working national scientific center.
A time standard established for British navigation in the mid-19th century. GMT has now been officially replaced by coordinated universal time, so Big Ben, the BT speaking clock and the BBC radio pips all mark UTC, not GMT as some people think -although the two are usually very close. British law still refers to GMT because a 1997 bill that tried to update it to UTC was never passed. It ran out of time.
The result is Coordinated Universal Time, the modern version of GMT.
In 1972, UTC replaced GMT because of the earth's changing rotational speed that results in our planet slowing down each year.
In the early 1960s, Greenwich Mean Time was replaced with UTC, which is set not on the Earth's rotation, but on atomic measurements.
It might also be worth mentioning astronomy parenthetically like "scientific research (especially astronomy)". Daniel Quinlan ( talk) 04:46, 8 February 2024 (UTC)It is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. Nonetheless, in specialized domains such as scientific research, navigation, and timekeeping, other standards like UT1 and TAI play a vital role.
