But since time compression affects past and present alike, it had also already happened in the future too....
Yes, it technically had already happened to everytime period, what I meant was that the only people whom would remember it happening would be those in the present and future. This is because it had not yet 'happened' in the past, so they wouldn't be able to remember something as being different when a post-time compressed world is all they knew. Those in the present remember because they saw it happen, and those in the future remember because they either saw it happen, or it's in history books

Remembering aside, Time Compression had left it's "/mark/" on all time periods since the beginning of time, and because of this it is impossible to see if Time Compression truly leaves a mark because a world without it does not exist in FF8.
