I have set up a calculated value field in a Nintex Form that gets the maximum date from a named Date/Time control in a repeating section, using the answer to this question.
Now I want to connect this maximum date to a Date and Time column on my SharePoint list. Is there a way to convert what's in a calculated value field into something SharePoint recognizes as Date and Time, or some other way to stick this thing in a Date and Time column?
