Well, apart from the fact that a day is not a year, there is no denying that between 0:00 UTC on one day and the next, there have elapsed 86401 SI seconds if there has been a leap second. > year with a leap second added has 86400 UTC seconds but 86401 TAI > seconds. Both UTC and TAI count SI-seconds, but you seem to differentiate between the two. How you want to express durations "in UTC" or "in TAI" is unclear to me and I prefer avoid it altogether.
