Commerce Order Status History
Try
{% set recentHistory = order.histories|first %} // get the first order history item
{{ recentHistory.dateCreated|date ?? 'no history record' }}

there is no date attribute on an order history model, just the dateCreated. So in effect you are passing null to the |date filter which will default to the current time/date.
You were trying to access the current order status model on the order. There is no dateCreated on the order status model, only the model itself. The date the order status was applied is in the orderHistory models.
