in thread Date and time difference

Well, if you can't install any CPAN modules, you could use a module that comes bundled with perl, namely POSIX. The below example code shows how to create a calendar time for December 12, 1995, at 10:30 am:

$time_t = POSIX::mktime( 0, 30, 10, 12, 11, 95 ); print "Date = ", POSIX::ctime($time_t);

Presumably you could create 2 calendar times and subtract one from the other using difftime, which will give you the difference in seconds - format as required for display.

UPDATE (small example):

use strict; use warnings; use POSIX qw(mktime difftime ctime); my $previous = '10111623'; my $current = '10111705'; my $time1 = mktime( 0, 0, $4, $3, $2 - 1, $1 + 100 ) if $previous =~ m +/(\d\d)(\d\d)(\d\d)(\d\d)/; my $time2 = mktime( 0, 0, $4, $3, $2 - 1, $1 + 100 ) if $current =~ m/ +(\d\d)(\d\d)(\d\d)(\d\d)/; printf("%s - %s = %d seconds\n", ctime($time2), ctime($time1), difftim +e($time2, $time1));

Output:

Wed Nov 17 05:00:00 2010 - Tue Nov 16 23:00:00 2010 = 21600 seconds
