A customer in a barber's chair sees the shop clock in the mirror facing him. The picture shows that reflection, numerals and all. What is the real time?

Reading the hands against the reversed numerals gives the real time directly: the minute hand is on (reversed) 8 and the hour hand is past 10, so 10:40. Equivalently, the hands sit where 1:20 would be on a normal face, and $11:60-1:20=10:40$.
