How to get a std::chrono::time_point representing [now]?

In order to get a std::chrono::time_point<std::chrono::system_clock> representing the current point in time, use std::chrono::system_clock::now()

std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();

Typically, you would use auto to avoid having to type out (or read) the long typename of std::chrono::time_point<std::chrono::system_clock>:

auto now = std::chrono::system_clock::now();
