@Sylphystia Thank you for reporting this! The error itself is harmless - it's just saying we're parsing a datetime without specifying timezone - so probably can be ignored for now, but feel free to update this issue if you see wonky behavior. I can think of places where the behavior would get weird (when admin announcements expire, edge cases with UTC vs local time when manually modifying chive create/update dates) so this is medium priority for a fix.
