Clock slew vulnerability in FreeBSD?

[Bnonn]

Is this technically a vulnerability, or is it just a side-effect of how 
computers operate? I was of the impression that this is quite an 
unavoidable issue, given how it seems to apply to any computer 
regardless of OS, but I haven't researched the issue much myself. 
Interesting question.
