Johannes123Today I noticed almost 900 posts of a wordpress page with about 6000 had the post_date and post_date_gmt fields set to "0000-00-00 00:00".
Additionally, when clicking Edit Post from the frontend the post's change date is sometimes set to "0000-00-00 00:00".
Updating WordPress to the newest version does not help. The problem has been happening for some time now, first posts having a zero date around May 2011.
My problem seems to be related to these two posts, however the proposed solutions don't apply here:

http://wordpress.org/support/topic/post-date-incorrect-year-showing-as-0000?replies=10
The system is running on a standard LAMP stack with an NGINX reverse cache.
Any help on this issue is greatly appreciated. I think we're observing a wordpress bug here.
Thank you,
Johannes
