SQL is a very limited computer language, most row-to-row comparison problems are more efficiently implemented in your app language: suck up the dataset into an array and do the logic there.

If you really want to do it SQL, there are duplicate times per serialnum & serialcode, so you'll need t provide criteria for selecting the row to keep per 30 mins.
