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

by:

  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.

Cheers,
David
