Maybe the RDTSC instruction might help for x86 processors, as it returns a number of ticks which is reset at startup. It is also extremely fast. Le 22 déc. 2016 13:04, "Thomas Dahms" a écrit : Dear developers, dear Ion, We are experiencing issues on Windows where boost::interprocess relies on a certain event in the system event log to get the system's boot-up time. This has proven to be unreliable, because that event is not always present in the log. In that case, initialization of boost::interprocess fails. Several bug reports exist for that issue, e.g. [1, 2]. Report [1] contains a proposed fix to use GetTickCount64() and there is an open PR with an alternative fix to fall back to WMI mechanisms [3]. I understand that the fix [1] would need some polishing, because GetTickCount64() is not available in pre-Vista. Nevertheless, both proposed fixes have been uncommented and unconsidered for a while now. Is there any chance that the maintainers could look into this? Thank you!
