Hello to all the knowing

Today I recognized my Calendar-Widget is kind of broken



Not only the widget doesn't show the current day correct (thin white line wich seperates today from future), but also yesterday. Also there are various errors with birthdays:

Werner: should be April 5th (today) - wrong - showed up as "today" yesterday
Gerhard: should be April 5th (today) - wrong - showed up as "today" yesterday
Birgit: should be April 6th (tomorrow) - wrong
Caro: April 9th - correct
Iris: should be April 10th - wrong
Annelies: April 13th - correct
Heike: should be April 14th - wrong

I've deleted and recreated Smart-Calendar in Stock-Application, deactivated and activated Birthdays in Widget, deleted and recreated Widged, edited Contacts and saved, rebooted - nothing changed. I do NOT sync Calendar with Outlook, Ovi-Suite, Google or something else, it's on my N900 only.
Birthdays are shown on correct date in Calendar-Application and stock-widget

Any idea
