> If you want to wreak havoc on a ZK based system just do [date -s "+1hour"] 
> and watch the mayhem as all sessions expire at once.
> This shouldn't happen.  Zookeeper could easily know handle elapsed times as 
> elapsed times rather than as differences between absolute times.  The 
> absolute times are subject to adjustment when the clock is set while a timer 
> is not subject to this problem.  In Java, System.currentTimeMillis() gives 
> you absolute time while System.nanoTime() gives you time based on a timer 
> from an arbitrary epoch.
> I have done this and have been running tests now for some tens of minutes 
> with no failures.  I will set up a test machine to redo the build again on 
> Ubuntu and post a patch here for discussion.
