Please demonstrate fictional date input [sample] in an authorised test environment. I intend it to mean [explicit year, month and day]. What is displayed on entry, after saving and reopening, and on export, and which date does each represent? What agreed convention is used to interpret month and day, and how is the user asked to clarify an ambiguous input? If display formats differ, explain how we can verify that they represent the same date. Do not alter real business records.
