The Olson now IANA database is where i get the leapseconds from.
But if it came with, say, NTP and made available via
a standardized system call (as via CLOCK_LEAPDRIFT) then user
space programs would be able to differentiate in between their
normal POSIX time, the TAI and the leap-second caused offset to
TAI.  All this self-synchronizing and in "realtime", an active
internet connection presupposed.
None of these is true for the timezone database.
