Zope 2.6.0 has a bug in DateTime.rfc822(). The bug appears when you are NOT in a DST timezone, causing a "Name Error: Global name localzone is not defined" error. This will affect many parts of your Zope operations, luckily, the fix is simple: - Download the fixed DateTime.py, from http://www.zope.org/Members/regebro/datetime_260_fix - Put the downloaded DateTime.py into the lib/python/DateTime directory, replacing the one that is there. - Restart the server. This fix is ONLY valid for Zope 2.6.0. Earlier versions of Zope does not have this bug, and this fix will be included in any future releases of Zope.
