Obsolete add-on; no longer usable.

The addon does not show the posted date of the video, not by day, month nor year.
Instead, it gives an approximate post date referenced by number of days or years since posting.

Hard for me to tell if it is doing what it's supposed to. But I was hoping it would revert YouTube's recent change in Date format (where it only displays how old the video or comment is in days or weeks) to show actual dates. Sadly, it does not.
