When I attempt to reason about what is possible and what is impossible 
in a program, I assume a sane universe.  Windows violates that 
assumption.  I am not responsible for what happens after that.

People complain that Python 3 has been out for 5 years and the world is 
still dragging its feet upgrading from Python 2.  NTP has been around 
for almost 30 years.

Keeping a bunch of clocks on a network in sync is a solved problem.  The 
world really needs to move on to new problems like how to deal with more 
than 2^32 devices on a network.  Or how to deal with languages where 26 
letters isn't enough.
