Prior Air Force, but not a pilot. 40 years later my internal clock is still usually accurate to 10-15 minutes. Not good enough to replace a kitchen timer, sadly

Prior Air Force, but not a pilot. 40 years later my internal clock is still usually accurate to 10-15 minutes. Not good enough to replace a kitchen timer, sadly. The saying when I was in was "If you're not five minutes early, you're late." Which I understand they have optimized to everyone showing up fifteen minutes early now. Such a time-waste.
