"Wakened by Mom, who was wittering about how there must've been a power failure for a couple of hours because all the clocks said 5:11. Except her clock, which has a battery back-up and saved us from the sin of tardiness. Her theory lost credibility, unfortunately, when I pointed out that the dining-room clock read 5:11 and is entirely battery-powered. A quick call to the Official Bank Clock Time Guy confirmed that it was, in fact, 5:11 and that Mom had changed the time on her own clock rather than setting the alarm. I have a feeling this will be one of those things that we never speak of again."
