Issue when pushing date values into portal using edit_features method

[Manager_HMWSSBCDC]

Hi, 

I have date values in my json. Now I want to push those changes into ArcGIS feature layer using 'edit_features' method. The feature layer contains date columns and time columns also. But during the push I observed that the feature layer not accepting date values in any format except in milliseconds example ('17408793488374')

Please guide me fix this.
