The FormConnect Pro app has the ability to calculate the difference in time between two date fields. All that is required is to create three fields and specify the third field as a “calculated field” that computes the time difference between the first two fields. This is done by entering a formula in the date calculated field.
Below are some screen shots that displays how this is done. There is also some help documentation on our web site that explains how to create a calculated field.
