6:00 start? What's that about?
Good question.
I assumed it has to do with the 10 p.m. to 5 a.m. curfew in the State of Ohio. I know most games with a 7 p.m. tip end around 9 p.m. But with media availability, some players needing to ice/injury evaluation or treatment it could stretch past 10 p.m.
No, there isn't a penalty, but as a state institution perhaps the university wants to be sure it is in full compliance with the governor's directive.
