Hi, In a trace, the time difference between two timestamps doesn't match the time it should have elapsed. For example, when measuring the duration of "sleep 1" in the trace, 0.358s is obtained. The real duration of the sleep is indeed 1 second. The error seems proportional to a constant factor.
I get this behavior on a 32 bits Ubuntu with 2.6.35-24-lttng from the PPA. I'm running the same version of kernel but configured with 64 bits and durations are correct. I put a sample trace here: http://secretaire.dorsal.polymtl.ca/~fgiraldeau/sleep-1x-1sec.tar.gz Seems a bug to me, or maybe I'm doing something wrong?
