My iCloud account was turned off can I find out what time this happened

My daughters I pad was hacked. The I cloud was turned off so the tracking system would not work. Is there a way to find out what time of day this happened.

I can at least let her teacher know what class this happened in. We were just lucky we caught it before it was stolen. Does anyone have any good ways to track iPad for parents. My daughter has Down's syndrome and really needs her iPad to help her with her class work.
