Why we have clocks

DS1 wanted to know how many seconds are in an hour. He got it right, but then I showed DS2 how many seconds are in a day (86,400) and how many in a year. But to count to 31 million and change, you couldn't sleep for a year and you'd have to count while you eat.

So DH said that's why we have clocks.
