You can use strftime :

        http://www.cplusplus.com/reference/clibrary/ctime/strftime.html
time_t now = time(0);
char timestamp[10] = "";
strftime (timestamp, 10,"%H.%M.%S", localtime(&now));

#include <sys/types.h>
#include <sys/timeb.h>

struct tm *current_time;

current_time = localtime(time());

char timebuf[20] = { 0 } ;

strftime(timebuf, 20, "%H.%M.%S", current_time);

asctime is another (fixed) way of formatting a time into a string. strftime allows you to choose the format, so you'll need strftime as I showed.

strftime already places its output in a string. In my example, the string is called timestamp. You can output it by adding this for example :
time_t now = time(0);
char timestamp[10] = "";
strftime (timestamp, 10,"%H.%M.%S", localtime(&now));
 
std::cout << timestamp << std::endl;                     // <--- this

Or if you mean you want it as an std::string, you can always create one from the timestamp buffer :
time_t now = time(0);
char timestamp_buf[10] = "";
strftime (timestamp_buf, 10,"%H.%M.%S", localtime(&now));
 
std::string timestamp = std::string(timestamp_buf);
std::cout << timestamp << std::endl;
