Description
When investigating a system undergoing larger system clock adjustments, I noticed that in some places, std::chrono::system_clock and std::chrono::high_resolution_clock are used for handling timeouts and status check intervals.
However, std::chrono::system_clock is definitely not steady, and std::chrono::high_resolution_clock is not steady quite often (see cppreference).
When undergoing clock adjustments (manually or due to clock server synchronization), timeouts and status checks might no longer be triggered when relying on timestamps based on std::chrono::system_clock.
