              dard extension)
       %Z     time  zone  (e.g., EDT), or nothing if no time zone
              is determinable
       By default, date pads numeric  fields  with  zeroes.   GNU
       date  recognizes the following modifiers between `%' and a
       numeric directive.
              `-' (hyphen) do not pad the field `_'  (underscore)
              pad the field with spaces

       The full documentation for date is maintained as a Texinfo
       manual.  If  the  info  and  date  programs  are  properly
       installed at your site, the command
              info date
       should give you access to the complete manual.
