Sky/Cloud Questions

So, this might be a stupid question...

I was wondering about the cloud/sky simulations. In many of your pics, I noticed that the sky looked very nice; with clouds, sun, and such. I was wondering if this was a constant texture, or if it was a dynamic simulation? For example, clouds staying in one place in the sky or slowly moving with progressive time of day, which brings me to my next inquiry: will there be a time of day? Sorry if this was already answered but I was just curious. Time of day that automatically progressed rather than having to be set (RoR's Caelum) would be awesome. Also settable time of day. Is time of day even implemented yet?

I'm not sure exactly why I care if the clouds move across the sky, but I thought it would add a sense of realism if it was already implemented/planned. Are the skies WIP or permanent?

EDIT: Another question: will the sky simulation be editable/vary with the map you use? The color/hue of the sky varies greatly in different parts of the world, and this would be a cool feature if here/planned.

I'm hoping for a dev response on this (tdev, gabester, estama LFSHutch) for a definitive answer. Thanks for your time.
