Dear Serene Monks,

My problem is this:

I would like to rearrange a list of data , to classify the list from the smallest hour to the latest hour

My list looks like :(* represents a data : number, ...)

* * * * * 02:50:00 * * *

* * * * * 01:30:00 * * *

* * * * * 05:40:00 * * *

Here is my code, but it does not seem to work.But I have no error messages. 
my %Hash;


    while (<INFILE>) {


    my $Line = $_;
        my @Elements = split(";", $Line);
    my $hour = $Elements[5];
    print STDOUT "L'heure vaut $hour\n";
        if ($Elements[5] =~ /^(\d\d):(\d\d):(\d\d)/   ){
        my $time = 3600*$1+60*$2+$3;
        $Hash{"$time"} = $Line;
        print STDOUT "the value of the Hash couple is $Hash{$time}";
        }
    }
    close INFILE;


print SDOUT "%Hash";
my @KEYS = keys(%Hash);
sort(@KEYS);

print STDOUT "The set of the keys is @KEYS";

my $hour_triee;
    foreach $hour_triee(@KEYS){
    print OUTFILE "$Hash{$hour_triee}";
    }

close OUTFILE;
