How to use nirsoft's BulkFileChanger's Command-Line Option to change a file's DateTime

Question

I cannot figure out how to change a win10 file's modified time using the command line option for Nirsoft's BulkFileChanger.exe There are examples on the information web page under the heading Using BulkFileChanger, Command-Line Options showing how to use a command-line statement to change a file's DateTime, but I apparently cannot figure out how to change a file's modified date. Here's the code I used in my failed attempt: "E:\Apps\NirSoft\x64\bulkfilechanger.exe" /ChangeTimeAttrSingle "E:\Apps\Delete01\test4 - Copy.bat" 10 0 I'd appreciate any suggestions about how to change a file's modified date using a command line operation. A python program would be best.
