I have what is hopefully a fairly simple question.
I am trying to run an OD cost matrix for every minute of a day for research I am performing. All of the settings will be the same for each run, except the time will change. I will be automating the process in Python. I know how to create a cost matrix with the settings, add the locations, and solve it all using Arcpy. However, I am hoping to be able to just change the time setting for each run without having to create a whole new cost matrix and add the locations again (similar to what you can do manually in ArcMap).
I have not been able to find a way to do this in Python (if there even is a way).
