I don't think this is supported internally.

Off hand, I would suggest you could look at the historical cib.xml files
(the old versions are stored as cib.xml.XX, iirc). If you can find the
file where the transition you're interested in happened, you could look
at the files mtime to get an idea of when it happened.

You could also parse the system logs, if the event you're curious about
happened recently enough.

Just a couple ideas, not sure how well they'd work in practice.
