    dontdisturbmycircles might be right, I never timed it. But daveb is certainly right. The answer I was looking for was the earth spinning on its axis. 15 seconds of arc per 1 second of time.

    There's a perfectly good reason why no one times clocks. It's based on assumption but it's pretty reliable :smile: even if you didn't have acces to any technology, you'd quickly be able to see whether your clock was accurate, just by going outside once in a blue moon, or if you worked by seeing the expression on your bosses face, either delight at you being so prompt or scorn at you being so late.
