Ok I am making a program that shows how long you were gone for basically.

It will send a message to a chat you are in every 5, 10, 20, 30, 40, 50, or 60 minutes (you get to pick the time)
I would like it to add up the total time they are gone (in minutes)
so if they are gone for 2 hours and they choose 30 it will add up in a label saying "60". and when you stop it, it will send a message saying "Back from idle gone for "time" minutes.

And if I can, Can I convert the minutes into like instead of "gone for 60 minutes" it would be "gone for 1 hour" (if not that's fine, that is just and extra I would like)
