Can I see specifically what time apps were used in Screen Time?

I can see how much time an app was used during the day on screen time, but I want to see at what time the app was used. My son's screen time shows an app was being used Friday, but he says it wasn't during class. So, I want to check the times he was on the app to make sure. How can I do that? I have an iPhone XS Max, he has a 6s.
