How can I set the time properties for a feature class or a layer via arcpy? For example, it appears that the layerTime classes are not available in Pro when compared to ArcMap?
A lot is different in on the mapping side
But for sure Joshua Bixby says no in this thread
and I can't find one either or a replacement in CIM
But, on a lark, have you just tried replacing 'mapping' with 'mp' ? I don't have a time-enable layer to check, perhaps it is just missing from the help docs
I'm not sure how long those items have been exposed in the CIM, but it's been at least since 2.5. Hope that helps! :)
