How do I change the date on saved documents in Word and emails in Outlook over a day old as they are all dated as 14/08/11?  I'm not sure what happened on 14/08/11 however anything over 2 days old has the same date listed and it makes it more difficult to distinguish in folders.

Help gratefully received!  I have checked the date and time on the computer and that is accurate.  It's the Microsoft office 2011 for Mac that is showing the date incorrectly.
in month view the date and time show against each event so that nothing but the date and time are visible thus rendering the calendar useless. How can I remove the date and time from the events in this view?
