Hellow monks, I have a problem rejoining after a Schwartzian. I'm doing this (reduced code): 
#!perl
use strict;
use warnings;

my ($mdate,$mts) = @ARGV;
my $recent =    (map { join "-", @{$_}[0..2] . " " . join ":", @{$_}[3
+..5] }
                 sort { $a->[0] <=> $b->[0] || $a->[1] <=> $b->[1] || 
+$a->[2] <=> $b->[2] }
                 map { [ split "[-: ]" ] } ($mdate,$mts))[0];
print $recent;

And, if I call with two dates in YYYY-MM-DD hh:mm:ss format I get the following result: 
david@eriador ~ $ ./comparer.pl  "2006-01-01 12:00:05" "2007-01-02 12:
+00:00"
01 12:00:05

If I only output the first join (map { join "-", @{$_}[0..2]), it works ok. Any ideas?
