>Support for time zones is optional, unless the time zone is reliably identifiable from the source in which case it’s obligatory.

Not to say that you already handle time zone correctly for some articles (for example: https://kirov-portal.ru/news/podrobnosti/avtobusy-ezdili-bolshe-menya-nichego-ne-zabotilo-chto-rasskazal-po-delu-o-pechnom-toplive-podsudimyj-direktor-zapravki-i-tajnye-svideteli-29090/ )
There's no reason to set correct time zone for some articles while leaving others.
