Package: libc6
Version: 2.3.6.ds1-13etch2

mktime returns 0x7fffffff for the year 2057.

I expect it fails on 32-bit time_t environment.

% cat t.c
#include <stdlib.h>
#include <stdio.h>
#include <time.h>

int main()
{
  struct tm tm;
  time_t t;

  printf("sizeof(time_t): %d\n", sizeof(time_t));
  printf("sizeof(long): %d\n", sizeof(long));

  tm.tm_sec = 0;
  tm.tm_min = 59;
  tm.tm_hour = 23;
  tm.tm_mday = 31;
  tm.tm_mon = 12 - 1;
  tm.tm_year = 2057 - 1900;
  tm.tm_isdst = -1;

  t = mktime(&tm);
  if (t == (time_t)(-1)) { printf("mktime failed\n"); exit(1); }

  printf("result: %ld (%lx)\n", t, t);
  printf("isdst: %d\n", tm.tm_isdst);
  return 0;
}
% gcc -Wall t.c
% ./a.out               
sizeof(time_t): 4
sizeof(long): 4
result: 2147483647 (7fffffff)
isdst: 0
