Hi,
You can use the "Date Increment" function to calculate what you need (see below)
Date Increment( :Col1, "Minute", :Col2)
Best,

If your col1 is a character column and not a JMP numeric DateTime column you will need to use this formula for the calculation
Date Increment( Informat( :col1, "Format Pattern", "<YYYY><-><MM><-><DD><hh><:><mm><:><ss>" ), "Minute", :col2 )
