When one has a bed in a secure spot, it should be possible to sleep until planetary morning, assuming that the planet you're on has a 'morning' that is some sane distance off. The monsters at night are much more challenging, and frankly it's just not as fun to not be able to see what I'm doing. I am not yet attired to go boldly exploring where I can't so much as see my own feathers! What constitutes a secure bed might take some defining... My current preferred base structure is relatively open, and occasionally hosts unwanted birds. This is probably not good enough. C'est la vie. I would adapt. I was surprised this hadn't already been suggested. Perhaps it has been. Did I use the wrong terms in the search box?
I agree with this suggestion. It would save me some time, though I usually make some coffee when my character sleeps at night. Another thing is that asteroids for example probably should not have a day or night time, as they don't really rotate the way a planet does, and perhaps some planets have an eternal dark side, like the dark side of our moon. Always covered in darkness. Which would make exploring it all the more challenging.
There is a lot of tools to avoid the darkness. I agree that exploring at night is boring and hard without the appropriate equipment. Contrariwise your suggestion, I think the developers should add more content for the night life of a planet, more random encounters, different vegetations that only bloom with the absence of light and another cool events. I like the night, it's an excellent time to build and/or dig I like having to wait for the sunrise, even more in Starbound, where you have to protect yourself of the coldness in some planets and don't have any restriction to sleep, like "there are monsters nearby", as in Minecraft. Sorry for my english
I think time should pass more quickly when you sleep but you take WAY more damage if anything attacks you. That would encourage only sleeping in safe locations. I also agree about some places not having day/night cycles and more exciting nights to promote exploring in the dark.
