The only hard part is converting the date to a format that can be easily searched. This can be done with a date conversion module (see above) or directly with a regex or split: 
use strict;

my %data;
foreach (<DATA>) {
    split(/ => /, $_);
    $data{@_[0]} = @_[1];
}

#######
my %months = ('Jan' => '01', 'Feb' => '02', 'Mar' => '03',
              'Apr' => '04', 'May' => '05', 'Jun' => '06',
              'Jul' => '07', 'Aug' => '08', 'Sep' => '09',
              'Oct' => '10', 'Nov' => '11', 'Dec' => '12');

foreach (keys %data) {
    $data{$_} =~ /\w+ (\w+) (\d+) (\d+):(\d+):(\d+) (\d+)/;
    $data{$_} = [$6.$months{$1}.sprintf('%02d', $2).$3.$4.$5, $data{$_
+}];
}
foreach (sort {$data{$b}->[0] <=> $data{$a}->[0]} keys %data) {
    print $_ . ' => ' . $data{$_}->[1];
}
