I'm trying to use the created_at_min option for fetching orders.
I would have expected this to return all my orders
orders = shopify.Order.find(updated_at_min="2008-01-01 03:00")
but it only returns 2
And when I do this, I don't get any orders at all, even though several orders have come in in the last few days
orders = shopify.Order.find(updated_at_min="2014-07-17 03:00")
Am I using the right syntax? And if I am, why are the right number of orders not being returned?
