Hm.

security proxies, of course, can't be persisted, so this would only  
happen if your datetime were proxied (which is completely reasonable).

Did you try just making a security declaration and seeing if that  
fixed the issue?  I haven't encountered the problem.  I would think  
you could just do something like

<class class="pytz.UTC">
<allow interface="zope.interface.common.idatetime.ITZInfo" />
</class>

I'm not sure where to put this in zope.app...maybe zope.app.interface?
