Converting between absolute and relative times with std::chrono
Until C++11, it was quite a hassle to take the wall clock time and just print it, because C++ did not have its own time library. It was always necessary to call functions of the C library, which looks very archaic, considering that such calls could be encapsulated nicely into their own classes.
Since C++11, the STL provides the chrono library, which makes time-related tasks much easier to implement.
In this recipe, we are going to take the local time, print it, and play around by adding different time offsets, which is a really comfortable thing to do with std::chrono.
