This one should come naturally while playing. My co-op partner unlocked this after sleeping at a safe house, essentially skipping the actual nighttime hours. I didn't unlock it until I actually played through an entire night cycle while active. One of the story missions early on makes you go down in the sewers at night, and that's an easy time to unlock this. Just make sure you don't sleep at a safehouse during the nighttime hours.
If someone in the comments could verify their unlock conditions, that would be great. It's possible the achievement just glitched in my buddy's favor.
