The shadows would be moving pretty fast with a 24 minute day. 48 minutes is OK.
I would like to see either shorter nights or longer sunrise-sunset transitions to total darkness, however. When I sleep at nightfall in RDR and get up 6 game hours later, it's still dark for several game hours, not so fun.
Also, a short day would be not so fun with a big map - if you have to drive a long way, a good part of the daylight is gone.
Shadows moved to fast in GTA IV even. I really want a day to be near 60 minutes, and I want the daytime to be a bit longer. I hated how short daytime was in IV, most of the time there was one of those really ugly orange sky colors that started at 14:00. I'd rather days be longer, it's Cali and it's the summer in the game, why not?

I think the duration of a day needs to coincide with the size of the map. If V's map ends up being like 3 times that of IV's map, for example, then it might make sense to extend the days from 48 to 60 minutes or 1 hour = 1 day. But who knows, 48 mins may be enough even with a much larger map.
I think that if you travel from LA to whatever the other cities are, you'd have shorter days to show that you had to drive "all night". If there is SF and LV [or simply San Diego] it would make sense to see the day change quicker to signify the distance.
