So the counting is not allowed to stop or to jump forward in case a time
server access by daemon changing the system time is not allowed to
interfere in any way.
So I suppose "GetTickCount (number of milliseconds since system start)"
would be OK, but MONOTONIC_RAW time does not _sound_ correct.
On Linux, "get_jiffies_64()" seems to be a decent Kernel call.
You can't use this in userspace.
