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

There's always the __TIMESTAMP__ preprocessor macro.

#include <iostream>

using namespace std

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

int main() {
    printBuildDateTime();
}

example: Sun Apr 13 11:28:08 2014

Answer 2

(For fellow googlers)

There is also Boost::date_time :

#include <boost/date_time/posix_time/posix_time.hpp>

boost::posix_time::ptime date_time = boost::posix_time::microsec_clock::universal_time();

Answer 3

http://www.cplusplus.com/reference/ctime/strftime/

This built-in seems to offer a reasonable set of options.

Answer 4

std C libraries provide time(). This is seconds from the epoch and can be converted to date and H:M:S using standard C functions. Boost also has a time/date library that you can check.

time_t  timev;
time(&timev);

Answer 5

The ffead-cpp provides multiple utility classes for various tasks, one such class is the Date class which provides a lot of features right from Date operations to date arithmetic, there's also a Timer class provided for timing operations. You can have a look at the same.

Answer 6

#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)

}
