I like this too. If a knob is too obtrusive/expensive, could do the same with two buttons. One button for forward and one for back. Make them sensitive enough that it's likely that a casual press will visibly scroll multiple minutes, but not too sensitive to prevent setting a specific minute with a quick tap.
