30.7.7 Class steady_clock [time.clock.steady]
namespace std::chrono {class steady_clock {public:using rep = unspecified; using period = ratio<unspecified, unspecified>; using duration = chrono::duration<rep, period>; using time_point = chrono::time_point<unspecified, duration>; static constexpr bool is_steady = true; static time_point now() noexcept; };}
Objects of class steady_clock represent clocks for which values of time_point never decrease as physical time advances and for which values of time_point advance at a steady rate relative to real time.
That is, the clock may not be adjusted.
