Roger, Currently the atime is not updated on a read, there are other circumstances where it is updated (touch I believe), but really won't help with what you are looking for. The reason this was not originally implemented was due to the overhead on the metadata. We recently have had a couple of questions about this and it is on the roadmap for 3, if we get a more requests we may be able to look at something shorter term (like update on an open).
