A very important point to expand on this is also that clocks
easily go out of sync, even in this day and age. For example, I have
one box that somehow loses (on average) seven minutes over a
three-week span. Probably something wrong with the hardware, I'm
sure, and I keep it running just because it's a puzzle for me.
However, while it may be an extreme case, it's by no means a rare
case. Unless everyone keeps in sync with the same atomic clock,
you'll always have wide variances. And even if they do sync up, they
would have to do so frequently (i.e. - daily).
