chrono usage wirh timezone

I have a duration as string e.g. "13:00:00" and a time_point parsed to a utc_time from an UTC time string using std::chrono::parse function.

std::chrono::time_point is slightly off

If I do the following:

std::this_thread::sleep_for with custom accelerated clock

I have many instances of std::this_thread::sleep_for(remaining_loop_time_duration)`.
