I think you may be overestimating how much people will care about the time difference. Simply put, it's extra additional context that will almost assuredly have to be put forward as a defense by you, after they have already formed their impression of you. I suspect such claims will come off as very hollow to most people who have become upset with you. You would probably be questioned about why you had not proactively removed and apologized for your old writings on your own, as soon as you "changed your mind" about the topic. This of course ignores that changes are often slow, and rather unlikely to prompt you to recall every single trace you may have left of your previous thoughts. But that's all squishy context that the internet has thoroughly shown it does not care for, nor even recognize most of the time.
