I see in the customizable text there are fields to customize the wording used for the timestamps but I am not sure if there is a way to change the format to show date and time. @codinghorror and the other main guys on here usually know exactly how to accomplish something and are very helpful in explaining it. In this case I am guessing there is no way since they haven’t told us. Seems like it would be a popular option for discourse admins but maybe not.
