If your machines switched dates yesterday it probably means you're
NTP infrastructure is insufficiently peered and diversified.

Quite correct!

BTW: one of the ways I discovered (almost by accident) to help make NTP more 
robust is to replace a set of lines such as:

  server  0.uk.pool.ntp.org   iburst
  server  1.uk.pool.ntp.org   iburst
  server  2.uk.pool.ntp.org   iburst


  pool  uk.pool.ntp.org   iburst

as NTP then selects the number of servers it thinks it needs and, IIRC, from 
time to time it will replace non-responsive servers with active ones 
automatically.  This is in NTP 4.2.6 and later.  Worth checking it out.
