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.

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;
};
