I think this choice of acronym predates the widespread use of the CSAM acronym when referring to CP. I don't know what it stands for either but I've always thought it was a play on words since in French, it sounds the same as "sesame" (sésame) which is the password to open the cave in Ali Baba and the Forty Thieves, and is used as an expression to designate an object that grant you access to something. But I have nothing to back this up.

What about using a dedicated calendar in the calendar app of your choice, set up events with reminder for every hour and repeat those events everyday ? You could then dismiss the notification once the task is complete.
