One second per second is harder than it sounds
I think the question is: when does it matter?  What applications rely on an accurate clock?  I guess it would matter if you are running some algorithm on logs that uses time as an input.  Interested to hear any other examples.<p>DJB has a clockspeed package that addresses this problem.  Anyone used it?<p><a href="http://thedjbway.b0llix.net/clockspeed.html" rel="nofollow">http://thedjbway.b0llix.net/clockspeed.html</a><p>It seems interesting but I haven't (yet) run into the need for super accurate clocks (or perhaps I am not running enough machines).
