Ariel, directed by Ron Howard, is a classic sci-fi film from 1989, not 1992, but another notable mention is 'Freejack' which was released in 1992 and stars Emilio Estevez as an assassin who is sent back in time to the present day.
This film explores themes of identity, free will, and the consequences of playing with time. While not a traditional space movie, it does feature a futuristic setting and elements of sci-fi.
If you're still thinking of another movie from 1992, it might be helpful to consider other films released that year, such as 'Under Siege' or 'Dazed and Confused'.
However, if I had to take a guess, based on your hint about space and time, I'd say the film that might be stuck in your head is actually 'Freejack', although it's worth noting that my knowledge is limited to films released before 2000.
