On my G3 calendar suddenly in agenda mode I got a one-day shift in the days of the week. see screen shot note October 5th AND October 6th are both shown as Sundays... BTW the calendar in all other modes (day, week, month, year) is perfect - no problem no shift. Obviously the Outlook base on the exchange server is also perfect. very weird - any suggestions?

 

Another hint is that the wrong date ends on October 27th: October 26th is both a Saturday and a Sunday on my agenda....
