std::this_thread::sleep_until (3) - Linux Man Pages
Defined in header <thread>
template< class Clock, class Duration > (since C++11)
void sleep_until( const std::chrono::time_point<Clock,Duration>& sleep_time );
Blocks the execution of the current thread until specified sleep_time has been reached.
The clock tied to sleep_time is used, which means that adjustments of the clock are taken into account. Thus, the duration of the block might, but might not, be less or more than sleep_time - Clock::now() at the time of the call, depending on the direction of the adjustment. The function also may block for longer than until after sleep_time has been reached due to scheduling or resource contention delays.
sleep_time - time to block until
Any exception thrown by Clock or Duration (clocks and durations provided by the standard library never throw)
sleep_for stops the execution of the current thread for a specified time duration
