IIRC, the "posix" ones are non-leap-second-aware.  Systems which have a
"right" directory have leap-second-aware timezone files in that
subdirectory.

As for how "right" it is to track leap seconds, I note that the powers
that control such things are seriously considering abandoning leap
seconds.  Having unpredictable future differences between UTC and TAI
sucks.
