You clearly don't understand how leap seconds work. You're embarrassing 
yourself now. When there's a leap second, there are 86401 SI seconds in 
that year, that's the whole point. You may also be interested to learn 
that a year with the similarly named leap day has 366 days, not the 
usual 365.

Nonsense. When there's a leap second, there's a UTC second numbered 
23:59:60, ibid. Both UTC and TAI tick forward constantly, with each new 
second uniquely enumerated.

Now there's a non-sequitur.
