This isn't primarily my discussion, but I agree with these three points 100%.
- human-day (following the Sun) = 86400 human-seconds (not equal to SI-seconds)
- human-day (following the Sun) = 86400 SI-seconds + an occasional
fudge factor (leap seconds)
- defining a scientific-day that is always 86400 SI seconds
Non acceptable solutions
- redefining the meaning of the human-day (such as simply removing leap seconds)
There is certainly nothing whatsoever wrong with TAI that I can see.
