In addition to this mail : when I try to acces creation date a message
appears in the IJ bar :

"unknown creation date format : 20100722 14:53:38.88"

and when I import my image with metadata in a result window, save that table
and then reopen it using import results, the table wich opens is still not a
Results table...and I can not access it (?!)
