The current time can be obtained by calling steady_clock::now(). There is no fixed relationship between values returned by steady_clock::now() and wall-clock time. }}} As far as I know, the C++11 standard does not make this requirement. It would be good to highlight this discrepancy in the doc, especially since the doc ""Included on the C++11 Recommendation"" section let's you think that boost's chrono and std's chrono are interchangeable."
