title: python equivalent of std::chrono::steady_clock::now();
body: <p>I am trying to convert a C++ code into Python.  What is the python equivalent that I can use to substitute <code>std::chrono::steady_clock::now();</code>that gives an accurate timing of the current time on linux that I can compare to other time points.</p>
  
  <pre><code>void takeImages(steady_clock::time_point next_frame)
  {
  
      steady_clock::time_point current_time = steady_clock::now();
  
      if (current_time &gt;= next_frame) {
          // do something if time right now is at or after next_frame
  }
  </code></pre>
