Answer 1

From the rdiff-backup(1) manual:

   5.     A date format of the form YYYY/MM/DD, YYYY-MM-DD, MM/DD/YYYY, or
          MM-DD-YYYY,  which  indicates  midnight  on the day in question,
          relative  to  the  current  timezone  settings.   For  instance,
          "2002/3/5",  "03-05-2002",  and  "2002-3-05" all mean March 5th,
          2002.
