[Zope3-Users] Re: question about request.locale and creation time

[Shailesh Kumar]

I tried solving this problem as follows. Don't know if its the best
solution, but works for me as my application is meant only for Intranet
environments.


   - I subclassed zope.app.container.browser.contents.Contents.
   - In the subclass I overrided _*extractContentInfo *method
   - Created a LocalTimezone class as described in Python manual by
   subclassing tzinfo
   - Converted the created and modifed datetime objects from dublin-core
   information to local time zone
   - Used this class to create the Container views

The time information looks now fine for me.

Is there any better way?

With regards,
-Shailesh
