Time passes. Things that require time happen. Eggs hatch, plants grow, batteries charge, water is purified, medkits manufactured and so on. The advance of time is same as waiting until next morning/evening. It's useful when recharging batteries, it can save your iife when you're nearly out of food or water and there's no more yet, you may speed up other things.

Also, likely a glitch - you can sleep in an unpowered base without air. If your base runs on solar power, you may just sleep until morning.
