Problem

"See my clock, Dad?  It's as bright as it can ever be!"  What was the
time?

My son just called me in to his bedroom, despite the fact it was well
after his bed time.  "What do you want?" I said.  "See my clock, Dad?"
he said "It's as bright as it can ever be!"

What was the time?

Show solution

10:08 pm (assuming pm is indicated).

Here is a graph of the number of segments illuminated versus minutes
past 12:00.
