Unclear on concept

I and looking at a recipe for some bread I plan to bake and I see the following times noted:

crusty bread
Prep time 
Cook time 
Total time 
No Knead Dutch Oven Crusty Bread – no kneading required, 4 simple ingredients, baked in a Dutch Oven! The result is simple perfection, hands down the best bread you’ll ever eat!
What they fail to take into account is the 12-18 hours needed to let the dough set up after mixing in the flour, salt, yeast, and water. You are not going to have a delicious loaf of bread in 50 minutes!
