--- Comment #9 from Jonathan Wakely <redi at gcc dot gnu.org> --- (In reply to frankhb1989 from comment #4) > For CLOCK_REALTIME, the Windows API GetSystemTimeAsFileTime is used. > GetSystemTimePreciseAsFileTime is an improved version which provide "the > highest possible level of precision (<1us)". Unfortunately, the latter is > only available since Windows 8/Windows 2012, which is not suited for > winpthreads for compatibility reason IMO. See this MSDN page for details: > http://msdn.microsoft.com/en-us/library/windows/desktop/hh706895(v=vs.85). > aspx But libstdc++ could call that directly, instead of going through the clock_gettime API.
