few days ago i changed the permalinkstructure in my blog (http://www.perun.net). And from this time my Feed (RSS 2.0) is going mad.
Every new posting is showed in Bloglines and Abilon (offline RSS-Reader) with the Date that is 3 months in the past eg. 04. January 2005. Some people told me that in Thunderbird the Date is xx. January 1970.
Atom and RSS 0.92 is OK. The Problem is only with RSS 2.0. But if i open http://www.perun.net/feed/ i cannot see any problem, the date and time is ok.
