Use a fixed date format string in CalendarExtensions.  This
should fix the breakage on Mavericks whre the date is not shown unless
it is today or yesterday. Affects message list pane and message info bar.
I think the date format string is not being fetched from user preferences.
typo
Use static format string for friendly date format, instead of
User Preferences, which does not work on Mavericks.
