Dates in the 1800s which are stored at 12:00 AM in a feature class in ArcGIS Pro appear as 12:03 AM when published to a feature service. I understand this is a&nbsp;<A href="https://community.esri.com/t5/arcgis-pro-questions/issues-with-historical-dates-pre-1900/td-p/411018" target="_self">known issue</A>&nbsp;with historic dates in ArcGIS and Microsoft Office, but allowing additional date formats besides UTC and allowing users to remove the timestamps would help resolve this discrepancy.</P><P>A similar issue is also discussed at&nbsp;<A href="https://community.esri.com/t5/arcgis-api-for-javascript-blog/timeslider-widgets-for-historical-or-geological/ba-p/1077255" target="_blank">https://community.esri.com/t5/arcgis-api-for-javascript-blog/timeslider-widgets-for-historical-or-geological/ba-p/1077255</A>.</P> Tue, 12 Oct 2021 06:25:48 GMT https://community.esri.com/t5/arcgis-pro-ideas/arcgis-temporal-features-time-sliders-needs-to/idc-p/1106602#M17302 LaurenWinklerCMU 2021-10-12T06:25:48Z
