I am trying to automate a certain workflow and in the process need to change the layer properties > Time > Layer Time to "Each feature has a single time field". I tried to create a separate python script outside the ArcGIS Pro environment, but failed to import the arcpy module. 

I have since tried to create a python notebook within ArcGIS Pro to connect to the layer, but I am unsure as to how to write the script to perform the above action. 

Additionally, will I be able to run this script from outside the ArcGIS Pro environment without having to open the aprx file? 

This is my code so far

import arcpy

# Setting the workspace (geodatabase or folder containing your data)

arcpy.env.workspace = r"C:\Users\manognat\Documents\ArcGIS\Projects\Workzone-Crash Association\Workzone-Crash Association.gdb"

# Setting the map document

aprx = arcpy.mp.ArcGISProject(r"C:\Users\manognat\Documents\ArcGIS\Projects\WorkZoneTest\WorkZoneTest\WorkZoneTest.aprx")

# Accessing a specific map in the project

map = aprx.listMaps("Map")[0]

# Accessing a specific layer in the map

layer = map.listLayers("LayerName")[0]

 

I  need the script to be able to automate the following functionality:

Right click on the layer –“LayerName”, then select Properties, then select Time, then set “Layer Time” to “Each feature has a single time field” and save.  

 

Any help is greatly appreciated.

Hello!

You should be able to enable time on a layer with the LayerTime Class. There are some sample scripts at the bottom that give examples:

https://pro.arcgis.com/en/pro-app/latest/arcpy/mapping/layertime-class.htm

From the documentation: The enableTime method on the Layer class allows you to enable time on a layer that has time information and therefore making access to LayerTime properties possible.
