By the way, there is currently no vDSO clock_gettime() exporting the LTTng trace clock for the ARM architecture. Therefore, we have to hit the kernel at every tracing site to read time. Someone should probably think of addressing that eventually in the LTTng kernel tree, at least for the most common architectures (e.g. omap) that provide a ccnt register that we can set so it can be read from user-space.
