Adobe Commerce DateTime attribute type is not implemented for customer attributes. They are date only. This causes an issue with being able to provide a customer with a full omnichannel experience of accurately viewing activity on how they interact with an organization outside of just their ecommerce purchases. With Date only and not DateTime for customer attributes, the activity of the customers interaction last interaction/transaction outside of Adobe Commerce - for example presentation of the last purchase in a brick and mortar location will be presented twice to the customer when other updates have occurred to the customer profile in Adobe Commerce.
