I have used the start and end question types in the first of a set of 3 nested repeats to determine the length of a visit to an inspection site. I assumed that the start question would capture the time when the top-level repeat was opened/created, and that the end question would capture the time when either a new top-level repeat was created, or when the survey was submitted by pressing the check mark button at the lower-right. See XlsForms.jpg for a snippet of the XLSForm.
However, the end time is the same as the start time when viewed in the underlying feature service in ArcGIS Online. See StartEnd.jpg.
What am I missing? All insights are appreciated.
