From what I've seen, it does do that (ie., almost like a pass-through between that range). I may be wrong, but I've had some results that have uploaded to my queue during various times within that 1 hour period, but still showed up at SETI as having uploaded at the time and day they acutally connected to the queue and not the next day.
[EDIT: Actually read the times your citing - yes - it'll be like a pass-through, but regarding what I mentioned, a similar thing goes on, but during a smaller time range]
