If TAI is a paper clock, what else should be used if a strictly monotone
time scale is needed?
And what makes UTC different from TAI to be a "real clock", as UTC is
derived from TAI by adding leap seconds?
Would a reverse definition of TAI (or rather TAI' ) by using UTC without the
leap seconds be a good enough approximation?
I'm quite sure i'm not the first one asking this question, but i couldn't
find an answer, neither with google nor in the time-nuts archives.
The trouble with you, Shev, is you don't say anything until you've saved
up a whole truckload of damned heavy brick arguments and then you dump
them all out and never look at the bleeding body mangled beneath the heap
