You will often see this if you start editing a page or create a post, but don't try to submit until a long time later. I've also seen a similar message trying to mark a page patrolled if I don't patrol it until a long time after I've clicked the diff link to look at it.

If it happens less than a few minutes after you submit from start editing or creating a new post, then I would be concerned, but otherwise it's doing what it's supposed to.
