IMO the timing doesn't really matter. The issue with late night snacking is that you're going to be asleep anyway, so there's no real need to feel satiated late at night. In terms of relieving hunger vs calorie intake, you're not getting much bang for your buck.

Moving the snack to another time in the day may help you feel more full throughout the day which is nice. But, absent of change in total calorie intake, I don't think it will make much of a difference one way or the other in terms of health or weight.
