GNU libc's implementation of gmtime/localtime returns NULL when tm_year would overflow. Also cf. the recent discussion on comp.std.c about asctime/ctime potentially writing beyond the internal buffer when the year is outside the range [-999, 9999] (although GNU libc's asctime does not have this particular problem).
