Arcpy - Create an Historical Marker on an archiving enabled dataset in Oracle SDE

Question

I am looking for a way to create an Historical Marker programmatically with arcpy.

The archiving is enabled on a dataset in Oracle SDE.

I think, it's related with arcpy Version Toolset, but I can't find the documentation about this.

#this is an non-working attemp because CreateHistoricalMarker_management() method does not exists
import arcpy, datetime

my_dataset = "c:\\gis\\connection_file.sde\\an_archived_dataset\\a_feature_class"
marker_name = "A new dummy marker"
marker_datetime = datetime.datetime.utcnow()

arcpy.CreateHistoricalMarker_management(my_dataset, marker_name, marker_datetime)

>>>AttributeError: 'module' object has no attribute 'CreateHistoricalMarker_management'

An answer took from Geonet Esri forum:

To create a Historical Marker from Python, an option is using comTypes. Following the next steps, you can create Historical Markers in a Enterprise Geodatabase from Python:

Environment: ArcGIS for Desktop 10.4.1 + Python 2.7

1. Install comtypes-0.6.2.win32.exe (attached)

2. Go to comtypes folder in "C:\Python27\ArcGIS10.4\Lib\site-packages\comtypes", and delete the automation.pyc, automation.pyo, safearray.pyc, safearray.pyo files. Edit the file automation.py and insert POINTER(BSTR): VT_BYREF|VT_BSTR, in the _ctype_to _vartype dictionary.

3. Delete all files in C:\Python27\ArcGIS10.4\Lib\site-packages\comtypes\gen

4. Copy the file Snippets.py (attached), into C:\Python27\ArcGIS10.4\Lib

5. From Python Script you must to implement a function to create the Historical Marker. (the example in the test.py file that can be found in Geonet Esri forum)
