Well we have seen Tsukuyomi condense like, 3 days time into to about 3 seconds and Danzo mentioned that Sasuke can't distort the perception of time with his genjutsu. Whether he means Sasuke himself isnt skilled enough to do it or his genjutsu is incapable of it isnt specified but regardless Itachi can effect perception of time.
