Thanks Andy.

I certainly did reply to the wrong email, apologies to all.


George.

Hi,

You seem to have hit reply on the wrong message so this appears in a

Rather than lower minsane to 1, it would be better if OP added at
least
two other servers (or used a pool, for providing the same). Although
it
says that this is for "critical applications", it's basically free to
do
so in most circumstances¹ and unless you do this you can't tell if
the
ntp server is correct or not (with two you can't tell *which* is
correct).

Thanks,
Andy

¹ I can see why some places may have policies about not using third
  party services, but if it is that important then hopefully such
places
  can justify having three local NTP clocks.

  The other thing people sometimes say to justify having only one is
  that they don't care if it's correct only that it's consistent
with
  all their other stuff. However I've found in real life that I
often
  want to correlate with events from outside my systems in which
case
  knowing that at least my stuff was synced to a global
understanding of
  time is valuable to me.
