C++ Language/Std/CRuntime/Time/PreciseTime
The current time obtained by std::time()
is appropriate for uses like the timestamp of a file.
But for a more precise measurement of time, set a std::chrono::time_point<std::chrono::high_resolution_clock>
object to the value returned by std::chrono::high_resolution_clock::now()
.
