I see this as a pretty interesting idea that could play as satire yet have a profound influence on the way people view "life".
It's essentially their world, their lives, that come to an end as they know it.
So what if the clock strikes 12:01 and they're still alive? They've lost everything and they become nomadic. What if they still see the world as being a post-apocalyptic version - the people getting in their cars every morning, go to work like zombies looking for food.
It's like they're regressing, going back to simpler times and at first, when they tell people that they have survived the apocalypse and were chosen to rebuilt society, people think they're crazy and living in denial.
But something happens: their simple life and ways begin to inspire others to do the same. We could see the joy of somebody actually carrying on a conversation - IN PERSON!! - and not over a phone. The joy of telling a story around a campfire - WITHOUT SPECIAL EFFECTS!
Against them would be the corporations and any entity that puts a value on money, wealth and greed. They become a threat to these people because what do corporations and the like do when people no longer put value in currency? Money doesn't mean anything to them any longer, other than it provides a good source for starting fires.
It would be fun watching this grow from the personal to a cultural and societal level.
