Additional Information

This defect will not be addressed as ArcGIS Online Assistant is not a supported method of configuring ArcGIS Online services. If the issue occurs via a supported method (i.e. Update Definition at the REST Endpoint), contact Esri Support Services as additional information is required for further investigation.

Workaround

Change the format of the date field in the JSON by using the ArcGIS Online Assistant. Change it to:

"format": {

              "dateFormat": "shortDateLongTime"

            }

Or make a full copy of the feature service using the ArcGIS Online Assistant. This automatically changes the format of date fields.
