title: Android NDK chrono epoch is not correct (std::chrono::high_resolution_clock)
body: <p>The code below does not print epoch.</p>
  
  <pre><code>typedef std::chrono::high_resolution_clock Clock;
  typedef std::chrono::milliseconds Milliseconds;
  auto res = std::chrono::duration_cast&lt;Milliseconds&gt;(Clock::now().time_since_epoch()).count();
  std::stringstream ss;
  ss &lt;&lt; res;
  printf("&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt;&gt; TimeUtiles::getTimestamp %s", ss.str().c_str());
  </code></pre>
  
  <p>I use NDK r9d and selected NDK toolchain version was 4.8 !</p>
  
  <p>EDIT:</p>
  
  <p>Changed <code>std::chrono::high_resolution_clock</code> to <code>std::chrono::system_clock</code>and it worked. Why? </p>
