This issue only appears when a feed item field feedItemUpdated date is set to October 31. Field is correct in feed item view, but gives an error at the portal_catalog.

When a feed item has its date set to October 31, if you go to to portal_catalog and browse getFeedItemUpdated,

portal_catalog/Indexes/getFeedItemUpdated/manage_browse

when you reach that feed item you get an Invalid date error:

Traceback (innermost last):

    DateError: Invalid date: (2013, 11, 0, 16, 24, 0, 'UTC')

As you can see date has been incorrectly calculated, and set to day 0 of November. Hours and minutes are some times changed (1 hour and/or 1 minute less).

You can reproduce this error just adding a feed item with date set to 2013/10/31.

This error leads some times leads to a database error,

2013-11-11 13:52:29 ERROR ZODB.Connection Couldn't load state for 0x25f1

tz = _TZINFO._zmap[tz.lower()]

and I have to recover from a database snapshot.

I have seen this too from time to time. I don't know if that was for feed feeder items or for general content types and standard date fields. Until now I have assumed this is a general error in Plone and you cannot always browse all indexes. I may be wrong.

Yes, it seems a general error but in Zope DateIndex.

There is a 5 years old report ticket in Plone stating that a ticket must be opened in Zope. https://dev.plone.org/ticket/8354

I have'nt found the Zope issue tracker.

If you save the living environment, the biodiversity that we have left,
you will also automatically save the physical environment, too. But If
you only save the physical environment, you will ultimately lose both.

  1. Don’t drive species to extinction

  2. Don’t destroy a habitat that species rely on.

  3. Don’t change the climate in ways that will result in the above.

Found the bug in Zope (cleder: thanks for the link) https://bugs.launchpad.net/zope2/+bug/727981. The issue is fixed in Products.ZCatalog 3.0b2.

I pinned Products.ZCatalog = 3.0.1 and browsed index getFeedItemUpdated without problems.

From my point of view this issue can be closed. Thank-you.
