Bug ID: 57641 Summary: std::timed_mutex.try_lock_until() is broken Product: gcc Version: 4.8.1 Status: UNCONFIRMED Severity: normal Priority: P3 Component: libstdc++ Assignee: unassigned at gcc dot gnu.org Reporter: mustrumr97 at gmail dot com It uses the duration since the time_point's clock's epoch. What if it's not the right clock? Different clocks may have different epochs. On my computer, the function works OK if the time_point is from high_resolution_clock but doesn't work if it's from steady_clock.
