UTC[edit]

Shouldn't it be Universal Time Coordinated? It makes more since because it's UTC not UCT. 4hrue2kd83f (talk) 14:29, 10 October 2018 (UTC)

No. See Coordinated Universal Time#Etymology. Jc3s5h (talk) 17:15, 10 October 2018 (UTC)

Error in "Future" section[edit]

Ladies, Gentlemen, please let me correct an error. "Future" section begins: "As the Earth's rotation continues to slow,...". But Earth is not slowing. In the last 60 years its rotational speed accelerates and decelerates, but there is not clear sign that in mean values accelerates or decelerates. Astronomers when say that Earth is slowing are referring to mean values of many centuries (see my talk page, section "Earth's rotation" for example). According to IERS/EOC plot Earth's rotation was exceptionally accelerating in last June, and decelerating in early September. Regards. — Preceding unsigned comment added by Georges T.

That plot is not suitable as a source, because it lacks axis labels, and because it is unattributed. Furthermore, it looks to me that it confirms the claim that Earth's rotational speed is slowing. The article has already noted that the rotational speed fluctuates.
I note that your user talk page is stuffed with incomprehensible original research on timescales; I don't want any of that finding it's way into the article, so expect any change you make to be closely scrutinised.
Incidentally, publishing your OR is not an appropriate use of a user talk page. Please see WP:Talk_page_guidelines#User_talk_pages. MrDemeanour (talk) 15:50, 10 December 2018 (UTC)
Mr. Demeanour, please accept my many thanks for your comment.
1. In plot, horizontal axis is years in gregorian calendar, and vertical is UT1-TAI in ms (msec, 0.001 sec), you can see it at the left of 36720.
2. Things are not as they look. Downward inclination in graph is due to that unit for TAI is sec SI, the mean sec UT1 of the year 1820 when Earth's rotational speed was fairly higher than last 60 and more years. For the same reason every leap second is positive. Indeed a graph TAI-UT1 is upward inclined. If you read carefully my presentation of Earth's rotation in my user talk page, then you could comprehend all that.
3. I do not expect edit the article.
4. What do you mean by OR? Regards. Georges T. (talk) 16:51, 10 December 2018 (UTC) (edited) Georges T. (talk) 15:06, 12 December 2018 (UTC) (also) Georges T. (talk) 15:29, 12 December 2018 (UTC)
"OR" refers to the "No original research policy, which information in articles that cannot be verified in WP:IRS is not allowed. Due to the nature of your talk page edits, you are being warned that any changes you make to the article will be carefully reviewed for strict adherence to policy.
