We are using a hosted feature layer that contains dates prior to 1900. I am using the ArcGIS Python API to save a queried feature set ( featureset.save() ) from this layer to a local geodatabase for analysis. All dates prior to the year 1900 are incorrect in the locally saved feature class. All other dates are saved with their correct UTC time. Using the Export Data option from the hosted feature layer using AGOL returns the correct results. Has anyone else experienced this, or know if this is a bug?
