Time - not returning correct day

[MethodMan]

#include <time.h>
#include <stdio.h>

main()
{
        time_t t;
        struct tm* local_t = localtime(&t);
        if (local_t != NULL) {
        printf("Day of the month: %d\n", local_t->tm_mday);  
        printf("Month of the year: %d\n", local_t->tm_mon);
        printf("Day in the year: %d\n", local_t->tm_yday);
        }
}

This should print out as specified by the printf statements, yet I get

6
3
95

Does anyone know what the problem can be?

Thanks

check this out.

Ive looked at it, but I dont see the problem besides it being statically allocated.

Im leaving work right now, I will take a look at it when I get home. Unless someone else helps out before then.

If you had actually read the link given to you, you'd see the correct way to use the function. You never put any value into t, so in effect, it passes random crap on to the other function.

In MSVC++, if I compile your code, the function returns NULL so your printf statements never execute.

How about actually calling time first?

If you would just read the info, its all there, with links to other interesting info about time.h. Here because I am nice is the way you want to do things.

#include <stdio.h>
#include <time.h>

int main ()
{
  time_t rawtime;
  struct tm * timeinfo;

  time ( &rawtime );
  timeinfo = localtime ( &rawtime );
  printf("Day of the month: %d\n", timeinfo->tm_mday);  
  printf("Month of the year: %d\n", (timeinfo->tm_mon) + 1);
  printf("Day in the year: %d\n", timeinfo->tm_yday);
                      //int tm_mon;    month (0 - 11 : 0 = January)
  return 0;
}

Thanks for the help!

[---snip exact example in the first link---]

If they didn't pay attention the first time through, what makes you think they will the second? It's nice to see someone make the effort to help, but you'd better slow down, you'll burn yourself out by the end of the week. Trust me on this, people never ever read links you give them. For example, there is a petition here to rename the FAQ to "NORT", or No One Reads This.
