I run the clockless household. Very liberating you all should try it. When the currawong calls I know I can go back to sleep. The magpie yodels me out of bed at dawn. Public transport is pretty much turn-up-and-go. Freedom from the grim chore of changing the car clock! Flights? Afternoon ones only.
I just checked and the microwave oven had the correct time, but I had to reset the usual oven myself.
