NO,there are 86400 atomic-seconds during the day; and living with 84600 seconds is ABSURD. Second is a part of SI BUT is not related to METRE - and hence the Metric System. We (if: I may use United States) not want is different or say we are NOT ready; since we DO NOT recommend going metric by Federal opinion.
Change is the law of progress! THINK TANKS must churn themselves rather say NO. Not discussing this topic on USMA is a matter of opinion.

Thirty days in July, September:
April, June, November, December;
All the rest have thirty-one; accepting February alone:
Which hath but twenty-nine, to be (in) fine;
Till leap year gives the whole week READY:
Is it not time to MODIFY or change to make it perennial, Oh Daddy!And make the calendar work with Leap Week Rule! ***** ***** ***** *****

I applaud mavi fibe's rejection of any suggestion that the metre be radically redefined.*
But I find his suggestion that the second be radically redefined equally objectionable.
I am interested in promoting SI metric, not destroying it by changing the well established and highly precise definitions of the basic units like either the metre or the second.
The problem seems to be decimalization of the way we measure time of day (in minutes and hours). Change the minutes and hours if you wish (they are not part of SI anyway), but leave the second (and the metre) alone.
There are 84600 seconds in an average day (it varies). Learn to live with it. My height and mass are 1.8 m and 71 kg. I'd like them to be nice round numbers like 2 m and 100 kg, but I certainly don't propose changing the entire SI system just so that someone (me) can have a couple useful numbers be simpler. The is no reason that the day needs to be some nice round number of units either, whether it's 24 somethings or 84.6 somethings.**
Regards, Bill Hooper ===================
* By radically redefined, I mean redefining so that the size of the unit is changed significantly. The metre and second have been redefined numerous times in the history of SI but those changes were always made in such a way that, to the precision available at the time of the change, the unit stayed exactly the same size. That kind of change is desirable when technology makes higher precision measurements possible. The kilogram is long overdue for that kind of change.
====================
**Divide up the day into any number of smaller units of whatever sizes you choose just as long as the net result is 84600 seconds. Name those other units anything you like. The 24 hours of 60 minutes each of 60 seconds is awkward (but well entrenched).
I've suggested here before that the day be divided into intervals called kiloseconds (ks), where 1 ks = 1000 s, and the day contains 84.6 ks. Neat, clean, doesn't mess with the basic SI second, and has just one awkward part (the number 84.6) to cope with. One awkward number is preferable to three (24-60-60) in the present system. I'm not promoting this scheme, simply suggesting that there are alternative the the disruptive schemes being proposed which change the second (or the metre).
Even that 84.6 factor can be partly ameliorated by any one of several plans. There are possibilities like 3 days of 84 ks and 2 days of 85 ks in each five day period. We live with months that are not all the same length; surely we could live with days that are not all exactly the same length. Alternatively, ten day "week: could consist of 6 days of 84 interspersed with 4 days of 85 ks. Or maybe lump all the 85 ks days together at the end of the 10 day week and make them a long weekend of four days each of which is extra long.
