How to specify a spatial reference in gdb?
You can specify the spatial reference in several ways: By entering the path to a .prj file, such as C:/workspace/watershed.prj. By referencing a feature class or feature dataset whose spatial reference you want to apply, such as C:/workspace/myproject.gdb/landuse/grassland.
How to check the modified date in Sde geodatabase?
It should connect to your SDE Geodatabase using the ArcPy class ArcSDESQLExecute and your connection file, then execute the SQL statement, return a list of records with the owner name, object type, creation date, and date last modified, then write the list to the output CSV file. Here is the output when I ran my script: And here is my CSV file:

How to create a feature class in ArcPy?
By defining a spatial reference object prior to using this tool, such as sr = arcpy.SpatialReference (“C:/data/Africa/Carthage.prj”), which you then use as the spatial reference parameter. The spatial reference of the Template Feature Class has no effect on the output spatial reference.
