Use std::strftime, it is standard C++.

#include 
#include 

int main ()
{
    std::time_t rawtime;
    std::tm* timeinfo;
    char buffer [80];

    std::time(&rawtime);
    timeinfo = std::localtime(&rawtime);

    std::strftime(buffer,80,"%Y-%m-%d-%H-%M-%S",timeinfo);
    std::puts(buffer);

    return 0;
}
