Days.

The group had been walking for days trying to find a shelter after Eclipse accidentally blew up the train everyone had been living out of. Yea, great going on his part... Now you were walking across the endless expanse of utopia turned dystopia that covered every inch of the earth. The smog from the city had long since coated the atmosphere, causing extreme cold in some parts of the earth, and extreme heat on the other sides of the earth. Luckily this city has temperature regulation. Your thoughts were probably interrupted my Eclipse's endless rambling, which visibly annoyed Solar (who was actually trying to watch out for danger.) a giant mechanical bird soared by overhead, tearing off large chunks of overgrown skyscrapers as its talons scraped the roofs. The loud noise seemed to snap Bloodmoon out of his daydreaming. And he glanced back at Sun and Moon. They seemed to be talking about how the giant birds were Afton robotics' way of scouting the city.

Other than the clatter of mechanical racoons duking it out for trash, it was pretty peaceful for the apocalypse.
