How to do it...

We are going to save the current time and print it. Additionally, our program will add different offsets to the saved time point and print the resulting time points too:

1. The typical include lines come first; then, we declare that we use the std namespace by default:

      #include <iostream>      #include <iomanip>      #include <chrono>            using namespace std;

2. We are going to print absolute time points. These will come along in the form of the chrono::time_point type template, so we will just overload the output stream operator for it. There are different ways to print the date and/or time part of a time point. We will just use the %c standard formatting. We could, of course, also print only the time, only the date, only the year, or ...
