Show time??

I would like to know how to display the time.
I know how to display the system clock
all I want is the time (eg hours/mins/secs)

Code:

---

#include <iostream>
#include <ctime>

using namespace std;


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

        time(&t);
        ti = localtime(&t);

        cout << ti->tm_hour << ":" << ti->tm_min << ":" << ti->tm_sec<<endl;
               
        return 0;       
}

---

#include <iostream.h>
#include <time.h>
#include <iostream.h>

void main()
{
time_t hold_time;
hold_time=time(NULL);
cout<<ctime(&hold_time);

}
