sprintf wants to print 3 numbers %4d, %2d and %2d.
sprintf expects them as 3 (!!) arguments, like sprintf
"%4d-%2d-%2d",2001,08,09;
but it receives something like sprintf "...",20010809,undef,undef.
You should use a RE to get the three different numbers:
sprintf "%4d-%2d-%2d", @data[0]-[17] =~ / (\d\d\d\d) (\d\d) (\d\d) /x;
