Hi All.
This is a bit off-topic, but people here are likely to know the answer.
V7 had a timzone function:
char *timezone(int zone, int dst);
that returned a timezone name. POSIX has a timezone variable which is
the offset in seconds from UTC.
The man pages for all of {Net,Free,Open}BSD seem to indicate that both
are available on those systems.
My question is, how? The declarations for both are given as being in <time.h>.
But don't the symbols in libc.a conflict with each other? How does a programmer
on *BSD choose which version of timezone they will get?
OpenBSD 7.3 only has "extern long timezone" and no timezone(3) function.
FreeBSD 14.0 only has the timezone(3) function (under _BSD_VISIBLE),
and doesn't set any variables.
