There is a Sleep Command, but the wiki states that it (probably) isn't for use on the Player (it does work with NPCs, I tried it).
From all I have read, it is not possible to force time to pass (other than fudges like the Fast Travel one) nor force the player to sleep ...
However, there are some console commands - as mentioned above - that do these jobs ... and so it is possible that SKSE will include such functionality in Papyrus soon (ish), I guess.
