[time-nuts] Win XP and NIST Time

For some reason, I always had trouble with the XP time service so I 
disabled it and added a different NTP demon.  I never had another problem.

As I understand it, NTP never does DST changes.  That's up to your OS to 
handle.  I live in an area that doesn't do DST changes so I've never had 
to deal with it - other than dealing with some WWVB clocks that don't 
let you disable DST!
