Привет!

Пытался собрать под RPi одну свою программу, обнаружил, что не проходит
один из тестов. В результате разбирательства столкнулся с какой-то совсем
уж странной вещью. Наверняка что-то простое и глупое, чего я не замечаю.

RPi4, Сизиф (обновился сегодня), aarch64, ядро 5.10.10-un-def-alt1

Минимальная программа:
-----
#include <time.h>
#include <stdint.h>
#include <stdio.h>

int
main() {
  struct tm ts;
  ts.tm_year = 120;
  ts.tm_mon  = 1;
  ts.tm_mday = 2;
  ts.tm_hour  = 1;
  ts.tm_min   = 0;
  ts.tm_sec   = 0;
  ts.tm_isdst   = 1;

  int64_t t0 = mktime(&ts);
  printf("%ld\n", t0);
  return 0;
}
-----

Результат выполнениия на x86_64:
$ make test_mktime
cc     test_mktime.c   -o test_mktime
$ ./test_mktime
1580601600

На RPi:
$ make test_mktime
cc     test_mktime.c   -o test_mktime
$ ./test_mktime
-1

Системное время везде установлено правильно.
