How to adjust time stamp using SETTIME?

While collecting the CSI data collection I am unable to synchronize the ap and sta. I am running the command:

"idf.py -p /dev/ttyUSB0 monitor SETTIME:123123123123"

I ran it in ./active_ap as well as ./active_sta in both of the scenario the output is as following:

Executing action: SETTIME:123123123123
ninja: error: unknown target 'SETTIME:123123123123'
command "SETTIME:123123123123" is not known to idf.py and is not a Ninja target

Kindly suggest the exact command and path to run the command!

This is how it was originally supposed to work:
Start by monitoring the serial data: idf.py -p /dev/ttyUSB0 monitor. Now that you have a serial connection between your computer (raspberry pi) and the ESP32, you can send data by manually typing characters and pressing enter (new-line). So just type SETTIME:123123123123.

However, looking back at this, the functionality was removed back in 2019 (7ac7243#diff-ce62f46368cba52d2223f182e1cfe46b4366274d06598d2784efe5ac35c9a9eaR217), so it is essentially deprecated and should be removed from the documentation. However, you might still be able to add input_loop(); to the main function of your ESP32 codebase.

TODO: Remove SETTIME from documentation and remove any remaining code fragments.

My suggestion is to capture the timestamp from the raspberry pi itself. Something like this: (https://github.com/StevenMHernandez/ESP32-CSI-Tool/blob/master/python_utils/serial_append_time.py)

Thanks a lot Steven!
