My original observation is in error as you will see.
Actually, I first edited /etc/ntp.conf to have use my
local time server first, and then tock.usno.navy.mil.
This time I had WireShark running when I first brought
up System Settings > Computer Administration section >
Date and Time. Merely bringing it up results is a
barrage of weird dns queries. Two I saw this time is
"settings-personal.desktop" and "settings-system.desktop".
Is you might expect, dns responded "No such name".
These things stop and then repeat every now and then.
On the Date and Time gui, if I uncheck and recheck "Set
date and time automatically" with my local url entered
and selected, I do get a correct ntp transaction.
I now see that the odd dns activity is not specifically
related to Date and Time, but occurs when I click and of
various options. Why is this?
