Paul (and the erlang-bugs list):

I had found the similar one (as I remember),
but the {{1969,12,31}...} part of
looks quite strange to me.
I cannot test the code since my 7.0R system
is TAI-based (zoneinfo compiled with LEAPSECOND flag).

How did you compile the program?
Mine is with the port (/usr/ports/lang/erlang),
with stock gcc-4.2.1 and HiPE disabled.
(I experienced a loading error of BEAM files
so I disabled the HiPE.)

Also I suggest you to test
for whether they provide symmetric results.
