The Monastery doesn't even record update times for most nodes. I plan to change that as part of my plans, but even that probably wouldn't help you as lots of changes are likely (at least initially) to update the time on a node even though the content hasn't been updated.

But most nodes around here just don't get updated.

You might consider implementing this on the client side of things by comparing content to detect updates.
