Time Cycle? 24 hour or shorter?

[SuperMorto]

I did a search for this but couldnt find a thread, what do you folks think about the time cycle? Will it be 24 hours or will it be cut shorter? Not sure if this has been confirmed or not, but I did a search.

My reason for asking is, I will only be playing late on during the week and can imagine it will be night, but I do know some games cut the cycle down to about 8 or 4 hours so players get night and day during one game session.
