The protagonist is transported to the time of The Best of Both Worlds: Part 2 (1990), but the Starfleet crew wear the uniforms introduced later in Star Trek: Deep Space Nine (1993). Incidentally, the prologue is set a decade after The Best of Both Worlds: Part 2 (1990) and those characters are wearing TNG costumes well after they were phased out.
