@movq@www.uninformativ.de (#pe5ymoa) It might be timestamps which are missing a timezone. In this case the spec says UTC must be assumed: if twt_date.tzinfo is None: twt_date = twt_date.replace(tzinfo=datetime.timezone.utc). I had to fix this in my implementation recently, too. Let me quickly provide a fix for the Python reference implementation in the spec.
