Mod(s) for 1 day = 1 day?

Are there any mods out there that would let me change how the in-game clock works so that it's always following the real time of day?

I'm not sure if things like saving without ending a day or having time pass while not playing the game are even possible for mods.

Also, I'm hoping to use this to play multiplayer, since that might make a difference.

I've been looking through mods, but everything that talks about realtime clocks seems to be very simple or something else entirely.
