Ok, I'll try and explain it a little better.
The input file contains details of transactions including time of transaction and total time taken. The desired output is the total number of transactions per time taken, broken down into hourly periods.
An example of the input would be:
07:01 blah blah blah 3 blah
07:03 blah blah blah 2 blah
08:02 blah blah blah 1 blah
08:05 blah blah blah 1 blah
09:10 blah blah blah 3 blah
And the desired output would be:
Time___________1 second_______2 second________3 second
07:00 - 07:59_______0____________1______________1
08:00 - 08:59_______2____________0______________0
09:00 - 09:59_______0____________0______________1
Which shows that between 7 and 8 there was one transaction that took 2 seconds and one transaction that took 3 seconds. Between 8 and 9 there were two transactions that took 2 seconds and between 9 and 10 there was 1 transaction that took 3 seconds.
Hope that clarfies it a bit.

css::dom::rule
CSS::DOM::Rule(3pm) User Contributed Perl Documentation CSS::DOM::Rule(3pm)
NAME
CSS::DOM::Rule - CSS rule class for CSS::DOM
VERSION
Version 0.14
SYNOPSIS
use CSS::DOM::Rule ':all'; # import constants
use CSS::DOM;
$sheet = new CSS::DOM;
$sheet->insertRule('bla blah blah {}');
$rule = $sheet->cssRules->[0];
$rule->type; # STYLE_RULE
$rule->cssText; # 'bla blah blah {}' or similar
$rule->cssText('p { margin: 0 }'); # replace it
$rule->parentStyleSheet; # $sheet
DESCRIPTION
This module provides the CSS rule class for CSS::DOM. It implements the CSSRule and CSSUnknownRule DOM interfaces.
METHODS
Constructor
Only call the constructor on this class to create an 'unknown' rule. You have to call the constructor on a particular subclass to get
another type. Normally you do not need to call this directly anyway. (See CSS::DOM's "parse" and "insertRule" methods.) But just in case
you do want to call it, here it is:
new CSS::DOM::Rule $parent; # unknown rule
require CSS::DOM::Rule::Style
new CSS::DOM::Rule::Style $parent;
# etc.
$parent is the parent rule, if the rule is nested, or the parent style sheet otherwise.
Object Methods
type
Returns one of the constants below indicating the type of rule.
cssText
Returns this rule's CSS code. If you pass an argument, it will be parsed as the new CSS code for this rule (replacing the existing
data), and the old value will be returned. This method will die if the replacement CSS code creates a different type of rule.
parentStyleSheet
This returns the style sheet to which the rule belongs.
parentRule
This returns the rule's parent rule, if there is one, or an empty list otherwise. There is only a parent rule if this one is nested,
e.g., inside a media rule.
EXPORTS
The following constants that indicate the type of rule will be exported on request (individually or with the ':all' tag):
UNKNOWN_RULE
STYLE_RULE
CHARSET_RULE
IMPORT_RULE
MEDIA_RULE
FONT_FACE_RULE
PAGE_RULE
