Resolved in this release:
Issue 102: an option to specify the date format in the "Received" column
It would be helpful to offer a list of example formats with a radio button or in a drop down list e.g.
M/d/yyyy "3/9/2008"
MM/dd/yy "03/09/08"
MM/dd/yyyy "03/09/2008"
dd/mm/yyy "09/03/2008"
ddd, MMM d, yyyy "Sun, Mar 9, 2008"
dddd, MMMM d, yyyy "Sunday, March 9, 2008"
This new feature should be added in File--> Options --> Miscellaneous.
