The created time field type will automatically show the date (and optionally, time) that a record was created. This applies to records created in any way, including records created manually in a table, records created via form submissions, APIs, and other integrations.

As with the date field, you can customize the date format, choose to include a time stamp, and choose whether to use the same time zone for all collaborators. Note that since the created time for a record will always be the same, there is no way to directly edit the contents of the cells in the created time field.
