The Clock on the Mantlepiece
I visited a friend one Sunday (I have friends – shocking, I know). I noted something unusual about his clock, other than the fact it was analogue, when the radio gave the time at the hour, the analogue antique was exactly 3 minutes slow.
“It loses 7 minutes every hour”, he told me, “no more and no less, but I’ve gotten used to it that way.”
When I spent a second evening with him later that same month, I remarked on the fact that the clock was dead right by radio time at the hour.
It was rather late in the evening, but he assured me that his treasure had not been adjusted nor fixed since my last visit.
What day of the week was the second visit?
