If you do want a new timescale, I think rubber seconds isn't going to be the solution.
One might point out that many time scales do rely on rubbery seconds, e.g., sidereal time and apparent solar time. If might be enlightening to step back from the tendentious and tedious tug-of-war between UTC and TAI and reflect that even UT1 - a mean solar time scale - intrinsically has rubber seconds. Sexagesimal notation is clearly revealed as a way to express an angle - of Earth orientation in this case. The whole point of UTC is to permit Earth orientation to be approximated while using SI seconds. Rob Seaman NOAO
