    UnixTimestamp to time

    I have the following code that takes a unix time stamp into a date.

    Code:
    #include "stdafx.h"
    #include <stdio.h>
    #include <stdlib.h>
    #include <time.h>
    #include <conio.h>
    //e.g. 1331812987 = Thu 15 Mar 2012 01:03:07 PM CET
    int main(int argc, char** argv) {
     struct tm * dt;
     char b[19];
     long ts;
     
     ts = 1331812987;
    
     
     dt = localtime(&ts);
     // use any strftime format spec here
     strftime(b, sizeof(b), "%c", dt);
     fprintf(stdout, "%s", b);
     getch();
     return 0;
    }
    Everything is right accept the HOUR of the timestamp which is 07 instead of 01

    is this fixable?

    According to http://www.unixtimestamp.com/index.php, 7 is the correct hour. Looks like it may be adjusting to the time zone of the computer.

    Yes localtime is returning the local time
    If you don't want that use gmtime instead.
    Debugging is twice as hard as writing the code in the first place.
    Therefore, if you write the code as cleverly as possible, you are, by
    definition, not smart enough to debug it.
