[Dev-C++] Compilation error

[Mohamed A. <mh...@gm...>]

Hi All, I get the following error when compiling my program. I have added
all necessary header files that I know but still getting the error.I would
appreciate your help. here is the portion of my code that it does not like

print_time(char *note)

 { struct tm *tm; struct timeval tv;
struct timezone tz;
struct timespec ts;
gettimeofday(&tv, &tz);
tm = localtime(&tv.tv_sec);

clock_gettime(CLOCK_REALTIME, &ts); printf("%s time is %i:%i.%ld\n", note,
tm->tm_min, tm->tm_sec, ts.tv_nsec);
}

here is the error
