timestamps is a hash containing at least one element that is an array reference. The array reference contains 5 elements containing array references. That is a horrible way to describe the structure so lets look at some code ways of dealing with it

use strict;
use warnings;

my %timestamps = (
    x => [
        ['2013-08-18T20:43:40Z'],
        ['2013-08-18T20:43:12Z'],
    ]
);
my $page = 'x';
my @edits = @{$timestamps{$page}};

for my $stamps (@edits) {
    for my $stamp (@$stamps) {
        print "a: $stamp\n";
    }
}

print "b: $edits[0][0]\n";
print "b: $edits[1][0]\n";
print "c: $timestamps{x}[0][0]\n";
print "c: $timestamps{x}[1][0]\n";

Prints:

a: 2013-08-18T20:43:40Z
a: 2013-08-18T20:43:12Z
b: 2013-08-18T20:43:40Z
b: 2013-08-18T20:43:12Z
c: 2013-08-18T20:43:40Z
c: 2013-08-18T20:43:12Z

I've only populated two of the time stamps, but that should serve to see how things hand together. Note the {} to access the hash elements and the [] to access the array elements, and that you can concatenate them as you like for whatever structure you have.

True laziness is hard work
