parsing and calculating difference.

Hi,

I have a file with the contents as following

Access Time: Thu Nov 6 16:43:45 2008
Modify Time: Thu Nov 6 16:43:45 2008
Change Time: Thu Nov 6 16:43:45 2008
Access Time: Thu Nov 6 16:43:02 2008
Modify Time: Thu Nov 6 16:44:01 2008
Change Time: Thu Nov 6 16:44:01 2008

I need to calculate the difference between two Access times. You can ignore the year and date.

just the difference between time stamps will do

Any ideas ??

Thanks,
Manohar

Time::gmtime(3pm)					 Perl Programmers Reference Guide					 Time::gmtime(3pm)

NAME
Time::gmtime - by-name interface to Perl's built-in gmtime() function SYNOPSIS
use Time::gmtime; $gm = gmtime(); printf "The day in Greenwich is %s ", (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $gm->wday() ]; use Time::gmtime qw(:FIELDS); gmtime(); printf "The day in Greenwich is %s ", (qw(Sun Mon Tue Wed Thu Fri Sat Sun))[ $tm_wday ]; $now = gmctime(); use Time::gmtime; use File::stat; $date_string = gmctime(stat($file)->mtime); DESCRIPTION
This module's default exports override the core gmtime() function, replacing it with a version that returns "Time::tm" objects. This object has methods that return the similarly named structure field name from the C's tm structure from time.h; namely sec, min, hour, mday, mon, year, wday, yday, and isdst. You may also import all the structure fields directly into your namespace as regular variables using the :FIELDS import tag. (Note that this still overrides your core functions.) Access these fields as variables named with a preceding "tm_" in front their method names. Thus, "$tm_obj->mday()" corresponds to $tm_mday if you import the fields. The gmctime() function provides a way of getting at the scalar sense of the original CORE::gmtime() function. To access this functionality without the core overrides, pass the "use" an empty import list, and then access function functions with their full qualified names. On the other hand, the built-ins are still available via the "CORE::" pseudo-package. NOTE
While this class is currently implemented using the Class::Struct module to build a struct-like class, you shouldn't rely upon this. AUTHOR
