Snape's Witch replies:

     This is an interesting theory. However after a careful reading, I'm convinced that the first three chapters of HBP take place on the same night at the same time.  'The Other Minister' opens "nearing midnight"; 'Spinner's End' begins with "the chilly mist that had pressed against the PM's windows drifted over a dirty river . . .": and Dumbledore appears at 4 Privet Drive at midnight in 'Will and Won't'.  In addition 'Horace Slughorn' follows immediately after 'Will and Won't'.
  
        
     Although a definite time isn't stated in 'Spinner's End' I believe that it is inferred because of it's placement between the lst and 3rd chapters. 
  
  
     If Snape is a polyjuiced Dumbledore then who is the man with Harry in Chapters 3 and 4?  Surely not Snape?  No, no, no.
