Need to see and calculate dates in Pivot Table

I am trying to do cycletime calculations in a pivot table. For each order there would be a step with a date it was completed. I would like to show those and add an additional field showing elapsed time between those dates. I have mocked up and attached an excel spreadsheet in how I would like it to appear.

My problem is I cannot seem to get dates to show in the body of the pivot table.

Is this possible?

Please add a sample sheet instead of a picture, containing the source data and an example of what you want to achieve
