AA
AA was a period of time on the planet Ventax II. It was mentioned in the  of the  fourth season episode , but not used in the episode. 

In the script, a legal precedent was set in 931 AA. That year, a case involved a contract dispute over services rendered by a Klingon craftsman on the construction of a Ventaxian home. As the case was between an alien claimant and a Ventaxian, both sides decided that arbitration rather than courts should decide the case. Both sides were required to chose an arbiter. The arbiter decided in favor of the Ventaxian. This was the only known case involving an alien claimant.
