In Alice in Wonderland the Hatter has a watch that doesn’t tell the time, it’s broken. This however is inimpoetant to the Hatter as it does tell the date, and since it’s always tea time anyway the date is the only unknown. I have the opposite problem when planning my time, I really only pay attention to the minutes which sometimes puts me in the irritating position of arriving an hour early, or late, and only realising when I get there.
But it’s still always tea time, so I’m off to get a coffee.
