use strict;
use warnings;

my %cols;
my %data;
for( <DATA> ) {
    /\s*(.*), (.*), (.*)/;
    $data{$2}{$3}=$1;
    $cols{$3}++;
}
my @cols = keys %cols;
print "\t$_" for @cols;
print "\n";
for my $time (keys %data) {
    print $time;
    for my $col (@cols) {
    print "\t", $data{$time}{$col}//"";
    }
    print "\n";
}
