This is how a clock with no numbers on its face looks in a mirror (the orange mark is at 12). What is the actual time?

Seen in the mirror the clock reads 7:50 (hour hand just before 8, minute hand at 10). The real time is $11:60-7:50=4:10$. 7:50 is the image itself; 5:10 and 4:50 come from mis-reading the hour or the minutes.
