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;  
}

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。

#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;
} 

c++与C共享它的日期/时间函数。tm结构可能是c++程序员最容易使用的结构——下面打印今天的日期:

#include <ctime>
#include <iostream>

int main() {
    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";
}

c++标准库没有提供合适的日期类型。c++继承了C语言中用于日期和时间操作的结构和函数，以及一些考虑本地化的日期/时间输入和输出函数。

// Current date/time based on current system
time_t now = time(0);

// Convert now to tm struct for local timezone
tm* localtm = localtime(&now);
cout << "The local date and time is: " << asctime(localtm) << endl;

// Convert now to tm struct for UTC
tm* gmtm = gmtime(&now);
if (gmtm != NULL) {
cout << "The UTC date and time is: " << asctime(gmtm) << endl;
}
else {
cerr << "Failed to get the UTC date and time" << endl;
return EXIT_FAILURE;
}
