Switching to `steady_clock` for walltime #436

Closed llaniewski closed 1 year ago

llaniewski commented 1 year ago

This PR switches the std::chrono::steady_clock::now() for walltime measurement in output and in log csv files. The previous use of ::clock() was really CPU time, and was giving misleading results.

This PR makes C++11 default.
