I wouldn't want the day/night cycle to move that quickly. That would make it feel even MORE like we were wasting tons of time when we're supposed to be dealing with urgent matters. Maybe 6 or 8 hours for a full 24 in-game hours.
I wouldn't be opposed to that. But I'd like to point out that while it
seems that those are short cycles (even the 2 hour one), in game it
feels much longer. I rarely notice time passage in BG1/2 unless travelling/resting. Since one wastes more time on movement in open worlds, perhaps 3 or 4 hour cycles might work. But I think longer ones would be unnecessary; it's also cool to notice the time passage without time skips and those 2 hours are enough to not make it seem like it just zips from dawn to dusk to dawn. Also note that we'd spend a considerable amount of time in TB - so frozen.
