Back Dating for retro league mod / cheat engine

I see a lot of people doing re-sims and i know it is kind of minor, but does anybody know of a way to get the correct year for your start date?

For instance I want to do a 30 year re-sim starting in the 89-90 season. I mean in my case i can use a little imagination and just subtract 30 since 2k started in 19-20 but just thought it would be more fun if it said the correct date.
