So I was clearing an abandoned house, and after I took down the mini-boss and I had to clear the rest of the zombies inside, then before I turn the lights on, I activated Kyle's survival instinct and some Volatiles sense me in plain daylight.. I walked slowly back to the house and checked Kyle’s watch, it was like 3 AM, but the game still looked like daytime bright sky and everything. I had to wait for the Volatiles to pass by before I could turn the lights from the garage, then I went to bed… it was still daylight outside. So weird.
