Time to think about what timing means to an ice. Say, in a busy restaurant there's the swingy kitchen door, if workers didn't "time" it right going thru that door it would be instant diaster.
Now, if the cook doesn't flip the burger, empty the frying basket, or clean the grill at the right "time" it would be disaster.
Or on the other end imagine if the waiter is taking all the orders and slipping them in randomly on the order carousel. The "timing" of what customer's food gets done first would be off.
Sadly, we are all bound by time some more so than others but in life timing is key.
