But the clock was broken in an interesting way. Not just dark. It would be dark for the count of five and then quickly flash a -- usually -- non-number. Interesting! For a couple nights, I tried to count along and then snap a photo at just the right moment. The results were not great. Eventually I remembered (again) the camera can take video. So, over a couple nights, I took video to capture the different things flashing. There are actually more than I thought there would be.

*You could argue that this clock was right once a day if you're using a 24-hour clock. But this clock -- when working -- is a 12-hour clock.
