As I understand it, TAI and UTC can both be described in terms of a
clock counting SI seconds. The difference is that a TAI day is always
86400 seconds long, whereas a UTC day can be 86399 - 86401 seconds,
depending on which second it is.
No, I believe a UTC day is also always exactly 86400 seconds long.
Incorrect.

Some seconds may be longer than others (though this happens only at
Leap Second events).  At least this is how it works in POSIX.
POSIX (stupidly) mandates that 86400 time_t seconds / day, yes.
