Im just thinking, every file have a date of creating, for replays this value is same with time, when the game started. So maybe if tus engine can read logs, maps, schemes from replay, could it also read the time, date of creating the file. So it will solve the problem I see usualy. That stuff as example: "We played this game 1 week ago, and he reported it just now, move it pls!", could it just move automatically to needed time, if tus really can read file properties.
edit:
Or just use date from name of replay, its much more easy to import, but also easy to cheat it :d
