I am using Survey123 I have both Start and End types(both esriFieldTypeDate) with a default of now() for both. When i record a new feature the date and time value is recorded just fine, but if I edit an existing feature it returns a value under Start of 12/31/1969, 4:00 PM. (<--issue) The End field is repopulated with a value of the time the edit its submitted.
I would think the Start field should either stay the same or repopulate to the date and time the feature opened for editing.
I also have a field called 'Install date'(esriFiledTypeDate)that is a date and time that is intended to be populated with values later and is currently set to type "hidden" in the XLSForm. this also returns a value of 12/31/1969, 4:00 PM when I edit a feature.
