Show the answer was left at 02:31:30 and the first (oldest) comment was left at 15:26:56 on the same day.. so first comment was left about 13 hours after the answer. No bug/time-travel here.
Have you refreshed the page? If you were on the page, left your computer and then came back, saw a "this post has new comments" and clicked it, it might do this. As far as I can see, the times are 16 hours ago for both answer and comment.
The screenshot is typical of having loaded the edit later on into the page after clicking on the this post has been edited banner, at which point the timestamp on it stops updating.
The question is, what do you see "now" when you go there and refresh? Hover the times if necessary ("11 hours ago" etc) to see the full timestamp. What do you see now? Sincerely, this is impossible. I know bugs exist, but a bug causing the issue you report would "likely" affect many questions given the scripts in play here will be reused around the site(s). We'd have (likely) a lot of people reporting and discussing this issue.
