Publishing date one hour wrong (Plone 6 Calssic)

espenmn · November 15, 2024, 9:39am

I have set my timezone to Europe/Oslo, but I get publishing date one hour 'too late' (see screenshots). Any suggestions?

I can confirm it happens in https://classic.demo.plone.org/ too.

Which timezone are you in? What 'offset' do you get ?

Europe/Rome, same as Berlin or Oslo I suppose. classicdemo has the same offset you saw, 1 hour later.

Have you configured the timezone on the server? If so, how?

It seem like 'that matters'. I changed the timezone and I think it is correct.

That said: That 'modified' and 'publication date' handles 'it' differently is not optimal

we usually set the server timezone to the client's timezone, and then we add the TZ environment variable in the instance configuration again with the same value.

          effective = schema.Datetime(

                  "not show up in listings and searches until this date.",
              ),
              required=False,
          )
          directives.widget("effective", DatetimeFieldWidget)

which does not consider the zone
