ffead-cpp为各种任务提供了多个实用程序类，其中一个类是Date类，它提供了从Date操作到日期算术的许多特性，还有一个Timer类用于计时操作。你也可以看看。

这个内置功能似乎提供了一组合理的选项。

#include <Windows.h>

void main()
{
     //Following is a structure to store date / time

SYSTEMTIME SystemTime, LocalTime;

    //To get the local time

int loctime = GetLocalTime(&LocalTime);

    //To get the system time

int systime = GetSystemTime(&SystemTime)

}

#include <stdio.h>
#include <time.h>

int main ()
{
  time_t rawtime;
  struct tm * timeinfo;

  time ( &rawtime );
  timeinfo = localtime ( &rawtime );
  printf ( "Current local time and date: %s", asctime (timeinfo) );

  return 0;
} 

下面是不弃用的现代c++解决方案，用于将时间戳作为std::string用于例如文件名:

std::string get_file_timestamp()
{
    const auto now = std::chrono::system_clock::now();
    const auto in_time_t = std::chrono::system_clock::to_time_t(now);

    std::stringstream output_stream;

    struct tm time_info;
    const auto errno_value = localtime_s(&time_info, &in_time_t);
    if(errno_value != 0)
    {
        throw std::runtime_error("localtime_s() failed: " + std::to_string(errno_value));
    }

    output_stream << std::put_time(&time_info, "%Y-%m-%d.%H_%M_%S");
    return output_stream.str();
}

localtime_s()版本:

#include <stdio.h>
#include <time.h>

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

  time ( &current_time );
  localtime_s(&local_time, &current_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;
}
