My first post -- about 2 weeks after trying out various flavors and birds of Linux, I have been using various networking performance tools. Then I noticed the following output of the lsof -i command this evening.
clock-app 1870 den 19u IPv4 28984 0t0 TCP den-Vista.local:51813->a23-59-191-27.deploy.akamaitechnologies.com:http (CLOSE_WAIT)

This suggests to me that the Clock 1.4.0 application in Linux Mint 14 MATE is using Akamai as an NTP (Network Time Protocol server) ??? As a newbie, I admit to being deficient in my understanding of Akamai but I thought one of their missions was to gather data and tracking analytics on folks for marketing purposes. I searched the Forum for Akamai, configuring clock-app and did not get any hits on those search terms.
When I went to the developer web site http://matsusoft.com.ar/projects/mate/ , I could not read it, but noticed the following table ~

Matsusoft MATE yes yes yes yes yes yes
(I'm new to this posting stuff, nearly 70 years old) Looks like they say there is a security hole with their clock software for MATE then? I searched the forum for their name Matusoft but also found nothing in the Forum. Surely tho I can't be the first person to notice this?
I have some experience in using several NTP programs in Win 7/XP that we use in amateur radio (hence the 'ham' in my name) for radio propagation delay timing and the like, and am used to choosing the closest NTP servers to me (like Univ of Wash.) But I don't remember Akamai being on the list of 'official' NTP time servers. I also saw some other ESTABLISHED and LISTENING ports I'm following up on but they aren't relevant to this post.
I also wonder why clock-app is using 5 different ports. I have two locations set in it for weather conditions -- where I live and also Seattle. The first time I ran the lsof -i command, the status was ESTABLISHED, i.e. active connection open.
The output below may not be relevant but I included it per my understanding of the Forum guidelines.
