Shall I store `datetime` or `DateTime` objects for Dexterity Date Fields?

How to set effective date in dexterity

I have tried this but this will cause other problems, e.g plone.app.layout.viewlets.content.isExpired if base_hasattr(self.context, 'expires'): return self.context.expires().isPast() will fail. And don't know about the indexing side effects.

Time zones in old DateTime objects

Thanks all for your help! I am going to try this out first and will report back, because 4.1.1 has what seems to be the exact fix I need. Changelog 4.2 (2017-04-26) Add support for Python 3.6, drop support for Python 3.3. 4.1.1 (2016-04-30) Support unpickling instances having a numeric timezone like +0430. 4.1 (2016-04-03) Add support for Python 3.4 and 3.5. Drop support for Python 2.6 and 3.2. 4.0.1 (2013-10-15) Provide more backward compatible timezones. [vangheem]
