The addons are not always up to date. I believe that check is simply the supported api version of the addon. Many addons don’t need to be up to date. Many times addon authors don’t change their addons at all after the game is updated and they only change this one line of supported api version so that the game reports it as up to date. I could be wrong. I wouldn’t worry if they are out of date. Just be sure they work without throwing lua script errors and they are fine. Enable the option to use out of date addons.
Minion is merely a utility that connects with ESOUI and runs automatic updates for addons with newer versions. Addon authors are a voluntary group of people, who contribute to the community on their own time.
It is called clock-Tamriel standard time, it still doesn't show up in my list of addons when playing eso.
