The same “kids across the street” I reference in another comment needed translation from “quarter to eleven” when they’d ask the time. Makes sense given they couldn’t read an analog face at the time.

My 18 year old daughter is the same (and also can't read an analog clock). Despite me using "quarter to," "quarter past," and "half past" regularly throughout her life. And we having analog clocks in most communal spaces in our house. And we drilled her on analog clocks for two summers in a row...

Similarly, when I moved from the UK to Canada, people often didn't understand what I meant when I said it was "half ten", which is the common way of saying ten thirty, at least where I grew up.
