    std::time_t t = std::time(0);   // get time now
    std::tm* now = std::localtime(&t);
    std::cout << (now->tm_year + 1900) << '-' 
         << (now->tm_mon + 1) << '-'
         <<  now->tm_mday
         << "\n";

#include <iostream>

time_t t = time(0);   // get time now
struct tm * now = localtime( & t );

ostringstream osTime;
osTime << (now->tm_year + 1900) <<
   (now->tm_mon + 1) <<
   now->tm_mday <<
   "\n";

cout << osTime.str();
