I'm so close to the last step, but....

What if you sort on two or three special columns? In my case date 11 and time 12. Is your original code limited to one column, our is it possible to "map" on more then one time/date format?

I've Googled and tried a lot last week, but I'm stuck (on the syntaxis).

my @sorted =
   map $_->[0],
   sort { $a->[11] cmp $b->[11] || #Date, original
   #      $a->[12] cmp $b->[12]    #Time, to do list
        }
   map [ $_, join('', (/(..)-(..)-(....)/)[2,1,0]) ],
   # map [ $_, join('', (/(..):(..):(..)/)[2,1,0]) ], # Is it possible
+ to map two columns date and time?

   @dates;  # DD-MM-YYYY
            # HOURS:MIN:SEC
