At 1:54 on the screen in Aurebesh, the Star Wars English equivalent of an alphabet, it says: "in 1,002 BBY". BBY stands for Before the Battle of Yavin, which takes place about 22 years after the events of this episode.
Admiral Trench's name is spelled 'Taranch' on Yularen's view-screen. This is because that was the original name used for the character during production.
