I have a document with a field _id has type ObjectId, and a field created_at has type Date.
_id is of course increasing, and the value of created_at is current_date should be increasing.
So my question is :
Is there any chance that 2 documents, A and B, A._id > B._id, but A.created_at < B>.
How to keep created_at as precise as possible, so the order of created_at corresponds to _id.

To mongodb sort by date you can use order_by on documents collection like
In Rails
Product.order_by("created_at desc")
In Mongodb for example
db.products.find().sort({"created_at": 1}) --- 1 for asc and -1 for desc
