How to get current time and date in C++?

Question

Is there a cross-platform way to get the current date and time in C++?

Answer 1

localtime_s() version:

#include 
#include 

int main ()
{
  time_t current_time;
  struct tm  local_time;

  time ( ¤t_time );
  localtime_s(&local_time, ¤t_time);

  int Year   = local_time.tm_year + 1900;
  int Month  = local_time.tm_mon + 1;
  int Day    = local_time.tm_mday;

  int Hour   = local_time.tm_hour;
  int Min    = local_time.tm_min;
  int Sec    = local_time.tm_sec;

  return 0;
}
