Hi Peeters,
I see it is FIELD object (with date). Have you created it yourself?
You need to start to edit this field (double-click text, select its contents -> Edit field from context menu) and find out what date it should to show by its definition. Is it "Create date" or "Date" or "Save date"?
What do you see when you start to edit field?
If everything is correct, use UPDATEFIELD command to update "Date" field as the Date field is only updated by UPDATEFIELD command.
