Dave, My observation is that the single system seems to work OK. The problem comes when about half the systems don't step at the same time, leaving the client without a reference clock (or sometimes with one) having two clusters about one second apart. As the leap-second propagated through, the population of these clusters changed, leaving clients confused as to the correct time. The one thing which stands out as making things much worse was the willingness of ntpd to discard a drift value which had been built up over many days too quickly - within an hour of the leap seconds drift values had shot to the limits (+/- 500) on some of my systems, and it was the recovery (in two cases failure to recover in a reasonable time), which was the major issue. I'd suggest that drift should not be changed by a large value, unless there is a good reason. No, I'm not an ntp expert!
