class steady_clock : public system_clock; RemarksA clock is monotonic if the value that is returned by a first call to now() is always less than or equal to the value that is returned by a subsequent call to now().A clock is steady if it is monotonic and if the time between clock...
In the STL (version 14.27.29009) included with VS Version 16.7.0 Preview 3.1, the steady_clock is not monotonic (the clock goes backwards after ~15 minutes). This is a critical bug which breaks every application using steady_clock. Windows 10.0.19042.330 on bare metal I can confirm that...
