For about two weeks, the clock in my living room stopped at exactly 3:17 every night.
At first I thought the battery was dying, so I replaced it. The clock worked all day, then stopped again at 3:17.
I bought a new clock. Same thing.
It became a joke between me and my girlfriend until one night we were both awake and watched it happen. The second hand reached 3:17 and just stopped. No sound. No flicker. Nothing.
A minute later, the lights in the apartment hallway turned on by themselves.
The clock started working again the next morning.
It stopped happening after we moved the clock to another room. I still do not know what was special about that wall.
