After Mr. Tysess's Sudden Reappearance in 2389, Q had him and some crewmates throw on this diddy.

It is believed he entered an anomaly with a shuttle in mid-2385. Upon returning, he said, "I guess I basically missed the late 80's."
Seriously, though, it surprises me how naturally Starfleet this guy sounds, especially after knowing him from another role. It just feels like he could be edited in to be some Ensign at Conn on a TNG-era bridge and no one would notice.
