How do you plan to display the process time? In a column of a grid, as a
label on a form, some other way?

You could just label a grid column "Process Time (seconds)" or some such,
but if you wanted to convert it to a Days:Hours:Minutes:Seconds string you
could add a computed column to the query and then set it in the
"OnComputedFields" event of the query.

If this isn't enough let me know and I'll send you some code.
