Would anyone have the code for real-world to Lusternia date converter? I know there's one accessible in the game, but I'd like to write up a macro in MS Word or Google docs to convert logs (with their GMT dates).

Pick a baseline date-to-date mark and then estimate that one hour of real time is one day of game time. That's basically what the game does, which is why it strays from actual on the farther-out dates.
