It's not random, It was an actual restore date that's not available anymore. It Doesn't matter, the check point would've been deleted.
Is their anyway to retrieve previous check points?
No. If they don't appear now, they can't be restored. YOu should try running CCleaner and going to Options > System Restore, it might have more SR points.
