You can format the date in a php page with the php date function. You would need to apply this to the recordset value for the date that is referenced in the 'create dynamic array' server behavior. Here is a link to the page that explains more about the date function:
To get the records to show in ascending order you will need to adjust the recordset that is used in the 'create dynamic array' server behavior. You will need to edit this recordset and set the order by, select the column, then set to ascending.
If you have any trouble with the date formatting post back withe the file in question and let me know the name of the date column and I can show you where this needs to be added.
