Yes, I would be happy to do that. However, reading timestamps in a tracer is a bit trickier than the average scenario, especially because of NMI context tracing. This is why I developed algorithms that keeps track of 64 bits counters that can be read atomically, even if the underlying hardware only provides a 32 bits counter. So I guess it would make sense to use the LTTng timestamping infrastructure for other uses, but the opposite is not necessarily true because of the reentrancy constraints. Mathieu
