Are u saying this as accepted in halachach or is this your personal sevara?
The generally accepted halachah is to permit Shabbos clocks; I am saying what I think is a simple distinction which even R’ Moshe, who assers Shabbos clocks, would agree with.
It’s clear that R’ Moshe didn’t have a problem with having a refrigerator on on Shabbos. If the normal cycling on and off of an appliance were the same as a timer, he would not have allowed it, as the compressor cycles on and off.
You can call it my sevara if you wish, but I think it’s a simple and clear distinction, and not really a chiddush.
