I copied the source to my own directory, and used it with snap.svg-min.js version 0.5.1. The animation failed: the minuteHand and hourHand are working OK, but the secondHand is not moving. I also saw this failure manifesting itself differently: the minuteHand was getting detached from the clock and shifting away.
The clock works OK for 0.3 and its URL is: https://oreillymedia.github.io/svg-essentials-examples/ch14/snap_animated_clock.svg
