I'm trying to validate an rss feed and I get an error saying "pubDate must be an RFC-822 date-time".
The date is in Turkish Sal, 07 Nis 2020 00:05:11 +0000.
If switched to English it validates. But it's a Turkish site...
I haven't been able to find any documentation saying RFC-822 is English only, but nothing with language information either.
