I would actually point to YouTube as a bad example. YouTube refuses to make the absolute timestamp available unless you actually navigate to a particular video's page. That makes it impossible to see which video uploaded "X period ago" is more recent from e.g. a search result page. Even if you don't _usually_ want an absolute timestamp, there's no reason to make it completely inaccessible in most places.
