The still shots of single video frames, presented in the Inquisitr article look ambiguous or incorrect. The month digit is unclear. It doesn't look like an eight and there is no other eight for comparison. Even the sixes (6) look different from each other in a given frame! The "six oddity" may be an optical illusion due to different hues of background imagery.
However, in context of the actual 1 min 30 sec video clip, CBS News surveillance video, the numbering
8 09 is very visible throughout the footage. The numbering is not unclear.
The scene is clearly a confrontation inside a store, although it is not entirely obvious what the altercation is about. Michael Brown shoves past, then turns on and shoves again, hard, a slight, middle-aged man who seems to be a worker at the store, trying to bar the door with his arm outstretched.
