Pressure king pro question re timer

[Whatjusthappenedthere]

Posting for a quick answer not an AiBU. Hope that’s ok.

Setting the timer on my new King Pro cooker, slow cooker function for dinner tomorrow evening.

Do I set the timer to reflect the start of cooking time or the end of cooking time??

My oven and washing machine do one or the other so I’m a bit confused as to what the Pro King might do ?

Anyone? bump

I’ve got a different brand of multi cooker but if I set the timer for 10 hours it comes on 10 hours later.
