Huh? Ok, I'm confused. I haven't had my license all that long, only 10
years or so[1]. At that time, digital clocks were quite common, but we
had to keep repairing those stupid analog clocks in the planes rather than
just sticking on a digital timer. I thought that was because of 91.205,
but on second thought it might just be because the analog clock is listed
in the POH as equipment it was certificated with.

Part of the issue is that your Westbend/RadioShack/etc timer isn't
installed in the airplane, so it doesn't count. What made the clock in the
panel magic was not that it had a second hand, but that it was mounted in
the panel.
