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.
