Is there a write-up on lttng timestamp precision?

I have noticed on a 4.10 kernel with a mix of kernel and usermode events
that the minimum time between events on a single software thread seems to be about 400 ns.

I noticed on this same system that clock_getres(CLOCK_MONOTONIC) reports 1 ns resolution.
