Try using time() and localtime(), thusly:

#include <time.h>

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

    time( &t);  /* t now contains seconds since 00:00 Jan 1, 1970 on UNIX */
    tm = localtime( &t);
    printf( "%02d:%02d:%02d\n", tm->tm_hour, tm->tm_min, tm->tm_sec);
}

"t" may have seconds (or some other unit) since some other epoch date on
non-UNIX systems, but localtime() should compensate for this.

Hope it helps...
