Good suggestions RL! However, although I have fixed the R2 shot in the latest version, the shot of 3PO alone has been cut as well as quite a few more changes. Probably best to just show the video and discuss below:

So in wanting to retain R2 waking up, it creates the necessity of some time passing yet there is no scene to fill the intervening time. That is why the change to night, and it also allows us to see the rings of D’qar from the ground which was a suggestion from another thread. The night color grade lightens up throughout the proceeding scenes until we see Rey watching over Finn the next morning, and I think it definitely reads as morning now instead of late afternoon.
