If the view put forward in Australia's document cited by Steve Allen prevails, something serious is missing. Every time scale I've ever heard of has a projection into the past, before the time scale was fully defined. Of course, the precision of such projections is limited by the available data, but people will insist on projecting every time scale into the past. So UTC abandons the insertion of leap seconds at time F. What shall we call the time scale which is formed by subtracting the desired number of SI seconds from F and, if desired, expressing as a Gregorian or Julian calendar date and time of day at quasi-Greenwich, where each day consists of exactly 86,400 SI seconds?
