RE: rolling back both connection

You did have to roll back Connections… Out of curiosity, since you did roll it back. Can you please upgrade just Connections to see if the issue starts again. That way I can rule out a change in Connections as the issue.

RE: Perhaps someone else besides me has the same problem?

So far this is the only reported occurrence. So, perhaps this is unique to your site for some reason. I’m certain we’ll get to the bottom of it in short order.

RE: Can you give me a hint where I can check the time zone settings?

The time zone setting is found on the core WordPress General settings admin page, right after the default language setting and before the date format setting.
