Giving total of Time duration in Data Table

I am storing some data about bookings.

So, there is a field called Booking Duration which stores the time(in seconds) for which the product was booked.

Is there any way I can show the total at the bottom of the table showing the total time for which a product was booked ?

If this total is possible, would it be possible to divide the total by 60(for time in minutes) ?

No this is currently not possible
