Sorry. I should have added a smiley or such.
I was thinking of the case where you had 2 servers and
one of them was off by many seconds (or many days). One
was clearly broken, but how do you tell which one?
Taking the average will guarantee that you get a bad time.
It will only be half as bad as the bad server but that's still
horrible on the scale of what NTP normally gets.
These are my opinions, not necessarily my employer's. I hate spam.
