ny_store_orders (order_id, ordered_at, amount) holds a New York store's orders. ordered_at is a TIMESTAMPTZ — an exact instant, stored and shown in UTC.
The store reports by its own calendar day in the America/New_York time zone: an order placed at 9 pm in New York belongs to that New York date, whatever the date is in UTC.
Return the number of orders per New York calendar date.
Columns: local_date (a DATE), orders. Sort by local_date.
