Why, then, does this test program work as expected:

#define _POSIX_SOURCE
#include <sys/types.h>
#include <time.h>
#include <stdio.h>

main() {
   struct tm *t;
   time_t tim; time(&tim);
   t = localtime(&tim);
   t->tm_year += 1900;

   printf("%02d.%02d.%04d %s\n",
	t->tm_mday, t->tm_mon+1, t->tm_year,
	tzname[t->tm_isdst]);
}

??? (TZ is unset. If it's empty, I get GMT which also works as expected.)

Well, the above impression (in a nutshell) was what I got when asking one of
the local people. If asking the local who's responsible for our licensing
stuff gets me a better answer, I'll ask him instead, no problem.  ;-)
