I am curios Wormley,you were pushing the 23 hour 56 minute 04 second value
even as your empirical colleagues were morphing to a new story,equally
vapid of course,that involves an idealized rotation once in 24 hours back in
1820 -

As I have explained, the NASA site you quote merely put aside the
complication that 24 hours is not the Earth's real rotation period to
concentrate on the fact that the Earth's rotation is slowing, so that
the day is getting longer. So they oversimplified by leaving out this
technical matter.

In no way is there any actual change from 23 hours, 56 minutes, and 4
second.
