There's been some discussion of removing leap seconds from UTC, as some
people need/want a more predictable and deterministic time scale. 
Given that International Atomic Time  exists, there doesn't seem to be
an easy way to reference it.
Is there any reason why a TAI "time zone" ("TZ=TAI; export TZ") is not
present for those that want to ignore leap seconds? I noticed that some
Linux distributions have a "right/" directory  to deal with this in
