You can use the Date::Calc module for this, like so:
Code:
#!/usr/bin/env perl
use warnings;
use strict;
use Date::Calc qw(:all);
my $line1 = '192.168.2.101 - - [14/Feb/2007:09:54:20 -0500] "GET / HTTP/1.1" 200 592 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.1.1) Gecko/20060601 Firefox/2.0.0.1 (Ubuntu-edgy)"';
my $line2 = '192.168.2.101 - - [30/Mar/2007:20:40:30 -0400] "GET /favicon.ico HTTP/1.1" 404 268 "-" "Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.8.0.7) Gecko/20061022 Iceweasel/1.5.0.7-g2"';
my %month_name = ( 'Jan' => 1, 'Feb' => 2, 'Mar' => 3,
'Apr' => 4, 'May' => 5, 'Jun' => 6,
'Jul' => 7, 'Aug' => 8, 'Sep' => 9,
'Oct' => 10, 'Nov' => 11, 'Dec' => 12 );
$line1 =~ m!\[(\d\d)/(\w\w\w)/(\d\d\d\d):(\d\d):(\d\d):(\d\d) [-+]\d\d\d\d\]!;
my %first = ( 'year' => $3, 'month' => $month_name{$2}, 'day' => $1,
'hours' => $4, 'minutes' => $5, 'seconds' => $6);
$line2 =~ m!\[(\d\d)/(\w\w\w)/(\d\d\d\d):(\d\d):(\d\d):(\d\d) [-+]\d\d\d\d\]!;
my %second = ( 'year' => $3, 'month' => $month_name{$2}, 'day' => $1,
'hours' => $4, 'minutes' => $5, 'seconds' => $6);
my ($years, $months, $days, $hours, $minutes, $seconds) =
Date::Calc::Delta_YMDHMS($first{'year'}, $first{'month'}, $first{'day'},
$first{'hours'}, $first{'minutes'}, $first{'seconds'},
$second{'year'}, $second{'month'}, $second{'day'},
$second{'hours'}, $second{'minutes'}, $second{'seconds'});
print "The difference is: ", $years, " years | ", $months, " months | ", $days, " days | ", $hours, " hours | ", $minutes, " minutes | ", $seconds, " seconds\n";
Assuming you haven't changed Apache's logging format for the date. |
