Who wants to check, add RecordTimer.py in /usr/lib/enigma2/python/ and restart enigma.
Just gave it a quick try, will give a more detailed test later (today/tomorrow).
It saved the timeshift file perfect (Just a quick test)
However, in my situation timeshift is running on usb/
so file was save to root of usb media/usb/
not media/usb/movie
Many thanks Colin
Will come back when I have more time
