I was visiting someplace that had an analog clock on the wall, and it was working fine but it was set to the wrong time (which I figured out later).  A broken clock is one thing -- you notice the hands aren't moving, the time hasn't changed since the last time you looked at it (which you keep checking because you're a dumbass).  But a clock set to the wrong time?  It's actively bad.  It's not just "not working".  It's giving you wrong information.  It seems like it's right because it's giving you an actual real time.  But that time is a lie, and now you're in a strange place with no idea what time it is, and you're an idiot for believing that lying clock.
