#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)

}

这适用于g++，我不确定这是否对你有帮助。 项目输出:

The current time is 11:43:41 am
The current date is 6-18-2015 June Wednesday 
Day of month is 17 and the Month of year is 6,
also the day of year is 167 & our Weekday is 3.
The current year is 2015.

代码:

#include <ctime>
#include <iostream>
#include <string>
#include <stdio.h>
#include <time.h>

using namespace std;

const std::string currentTime() {
time_t now = time(0);
struct tm tstruct;
char buf[80];
tstruct = *localtime(&now);
strftime(buf, sizeof(buf), "%H:%M:%S %P", &tstruct);
return buf;
}

const std::string currentDate() {
time_t now = time(0);
struct tm tstruct;
char buf[80];
tstruct = *localtime(&now);
strftime(buf, sizeof(buf), "%B %A ", &tstruct);
return buf;
}

int main() {
    cout << "\033[2J\033[1;1H"; 
std:cout << "The current time is " << currentTime() << std::endl;
    time_t t = time(0);   // get time now
    struct tm * now = localtime( & t );
    cout << "The current date is " << now->tm_mon + 1 << '-' 
         << (now->tm_mday  + 1) << '-'
         <<  (now->tm_year + 1900) 
         << " " << currentDate() << endl; 

 cout << "Day of month is " << (now->tm_mday) 
      << " and the Month of year is " << (now->tm_mon)+1 << "," << endl;
    cout << "also the day of year is " << (now->tm_yday) 
         << " & our Weekday is " << (now->tm_wday) << "." << endl;
    cout << "The current year is " << (now->tm_year)+1900 << "." 
         << endl;
 return 0;  
}

#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;
} 

ctime std::

为什么到目前为止只有评论提到了ctime ?

#include <ctime>
#include <iostream>
 
int main()
{
    std::time_t result = std::time(nullptr);
    std::cout << std::ctime(&result);
}

你也可以直接使用ctime():

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

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

  time ( &rawtime );
  printf ( "Current local time and date: %s", ctime (&rawtime) );

  return 0;
} 

总有__TIMESTAMP__预处理器宏。

#include <iostream>

using namespace std

void printBuildDateTime () {
    cout << __TIMESTAMP__ << endl;
}

int main() {
    printBuildDateTime();
}
