OK. My mistook.

I did a quick scan yesterday (details not near me now) of some of the auto
builds, and a not-bleeding-edge but "recent" version -- I think it was
swipl-5.4.7 -- seemed to build fine under fbsd6.{0,1}
with none of my hacking.

But I'll check the details and get back to you.

I've found various reports of similar problems with other software.
Bottom line appears to be that timezone variable is simply lacking and
one should use the tm_gmtoff of struct tm. With help of provided patches
and work-arounds in other systems I think I managed to get a working
version. At least it compiles on both Linux and MacOS 10.4. Linux
provides both interfaces and they give consistent results. Patches
are on the SWI-Prolog CVS server.
