Where can I find the GCC 9 implementation of std::chrono::system_clock::now()?
Question
The chrono system header ( /usr/include/c++/9/chrono ) declares, but does not define, the static now() functions of its clocks. I also do not see an include that looks relevant. Where are these functions implemented?

Where are these functions implemented?
In your C++ standard library implementation.
GNU compiler is shipped with GNU C++ library - libstdc++ . Inside gcc source tree, you may find libstdc++-v3/chrono.cc file with the implementation of chrono::now() function.
