One oddity; AIX had a preference for CUT with fallbacks to CUT0 and UCT
back when we had AIX boxes (5.2 or 5.3, if my memory still works on this).
We wound up setting PGTZ explicitly to UTC to overrule any such fighting
between time zones.
There may therefore be some older history (and some sort of inertia) in AIX
land than meets the eye elsewhere.
That doesn't prevent it from being a good idea to talk to tzdb maintainers,
of course.
