Feeding a date to a Custom Action function

Feeding a date to a Custom Action function

From a view I need to modify several records at a time based on a date. I want the user to check the records in the view and then call a custom action that asks for the date and then performs an action on each of the checked records.

I am feeding the checked records to the function as a form object. What is the best method of getting the date for the function?
