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

int main(){

time_t now = time(NULL);
struct tm *now_s = localtime(&now) ;

if(now_s == NULL)
return EXIT_FAILURE;

printf("%d-%02d-%02d %02d:%02d:%02d\ n", 1900+now_s->tm_year, ++now_s -

>tm_mon,

now_s->tm_mday, now_s->tm_hour, now_s->tm_min,now_s->tm_sec);

return EXIT_SUCCESS;
}

Bye.

In C, time() gets you the current date/time in a time_t format.
Various functions can get that into a printable string format:

ctime()
localtime() followed by strftime()
localtime() followed by asctime()
