The definition of localtime was quoted in my first post from the man page

struct tm *localtime(const time_t *timep);

but I mistakenly removed the argument and the warning was generated because
of the unknown function localtime (because its definition in time.h wasn't
included - see other response). Nothing to do with Perl, BTW, Kevin - the
real program has


tp = localtime(&tbuf.time);
tdiff = TIMEDIFF - tbuf.timezone * 60;
if (tp->tm_isdst)
   tdiff += 60 * 60;
   
The question of why sys/time.h is not including time.h remains open.
