It might be more subtle than that. One of these cases is discussed in aDebian mailing list thread, where one user claims his hardware clock runsso poorly, it loses second every hour, and he doesn't have problems.ntp normally drifts to adjust time; for exceptional jumps in time, it won'tdrift, but just set.
There's another thread of bug reports on Oracle servers (linux based) whichappearently hit the same problem, although they think it has something todo with a backwards leap-second jump.
