Pro ArcPy - Creating Time Slider from Layer

Hello everyone,

I am currently trying to connect temporal data from a particular data table from ArcPy to my XY data and am having a bit of trouble. This forum post got me a good starting point, but I'm a bit stumped from here.

I am essentially trying to replicate the functionality when you do the following actions:

Click the relevant data table
Go to Settings
Click Time
Assuming you have a column "timestamp":
1. Set the data column as such
2. Set unique value for each time point
3. Set the time format (i.e. "yyyyMMdd")

This generates a time slider on top of the data.

I manually investigated the data fields using the Python window and tried to reconstruct the code necessary to reproduce it from scratch. I came up with the following code, where "example1" is a data table that has the fields "latitude", "longitude", and "timestamp." The "timestamp" field is in format "yyyyMMdd."

import arcpy p = arcpy.mp.ArcGISProject("CURRENT) m = p.listMaps("Map)[0] l = m.listLayers("example")[0] l_cim = l.getDefinition("V2") ft = l_cim.featureTable ft.timeFields = arcpy.cim.CIMVectorLayers.CIMTimeTableDefinition( startTimeField="timestamp", timeValueFormat="yyyyMMdd" ) timeReference = arcpy.cim.CIMExternal.TimeReference() customTimeExtent = arcpy.cim.CIMExternal.TimeExtent() ft.timeDefinition = arcpy.cim.CIMVectorLayers.CIMTimeDataDefinition( useTime=True, timeReference=timeReference, timeExtentCanChange=False, hasLiveData=False, customTimeExtent=customTimeExtent ) ft.timeDisplayDefinition = arcpy.cim.CIMVectorLayers.CIMTimeDisplayDefinition( cumulative=False, timeInterval=10, timeIntervalUnits='esriTimeUnitsUnknown', timeOffset=0.0, timeOffsetUnits='esriTimeUnitsDays', uniqueTimes=[] ) ft.timeDimensionFields = arcpy.cim.CIMVectorLayers.CIMTimeDimensionDefinition() l_cim.featureTable = ft l.setDefinition(l_cim) l.enable_time() p.save()

From what I can tell, this creates a CIM that matches the corresponding CIM that was created when I made a Time Slider in the UI. I checked this through the interactive Python window in ArcGIS Pro. When I do this through the Python script, a Time Slider is created, but it does not connect with the data. When I disable time in the UI, the points appear, but when I enable time, everything disappears.

Can anyone direct me to any documentation for this? I'm a bit stuck right now. Thanks.
