The BBC article says: But the clock is only accurate once every five minutes - the rest of the time the lights are simply for decoration. The wikipedia article on the Grasshopper escapement http://en.wikipedia.org/wiki/Grasshopper_escapement links to an AP article that says: Weirdly, the clock's pendulum slows down or speeds up. Sometimes it stops, the chronophage shakes a foot and the pendulum moves again. Because of that, the time display may be as much as a minute off, although it swings back to the correct time every five minutes, said Taylor. If the pendulum stops, how does it know when to start up again? Is the visual pendulum just decoration with the real timekeeping done by some other mechanism? -- These are my opinions, not necessarily my employer's.
