My suggestion is to first stack the columns and then create the delta column

Assuming the Start and End1 columns are true JMP date/time columns, all that has to be done is to use the formula
:End1 - :Start
and then set the format for the new column to one of the Duration formats

Thanks for your reply. 
I have several columns for "Start Date" and I want all the deltas to appear in one column.

once it will take the ":End1 - :Start" and once ":End2 - :Start".

How can I do that?
