Here's how it's done on windows. If you need a different time format
you'll need to use localtime and strftime.

#include <stdio.h>
#include <time.h>
#include <windows.h>
int main() {
	for(;;) {
		time_t t = time(NULL);
		char *str = ctime(&t);
		str[24] = '\0'; /* remove the newline from string */
		printf("\r%s", str);
		fflush(stdout);
		Sleep(500);
	}
}

To sleep on unix, use the following code (requires time.h):
struct timespec ts;
ts.tv_sec = 0;
ts.tv_nsec = 500000000L; /* 500 million ns = 500 ms */
nanosleep(&ts, NULL);
