How do I know when a customer made their selection for a date or time on an order?
Supertime will add a "Supertime Selected" attribute that will have the date and time that a customer made their selection in the cart page. This should help provide more insight into the checkout process and diagnosing edge cases with certain customers that selected a date and then take a long time to checkout (or for stores with abandoned carts enabled).
You can disable the "Supertime Selected" attribute by visiting your settings.
