How to get the lines matched of a file in perl?

Hi,

I want to match the time in the file and retrieve those contents of the file.

I am taking only first two parameters of localtime(time) function minutes and seconds so partial match i am performing.

For Example

Code:
$start = "14:23";
$end = "14:30";

I am matching file contents with this time but some times it matches start time or end time or both all the cases i am considering it.

If start time is not matching then if end time is matching it should retrieve both the lines of start time as well as end time.

For example: Here are the file contents:

Code:
14:23:00,14:25:16,0,0,0
14:25:03,14:27:00:16,7,0,0
14:25:00,14:30:16,5,0,0

It should retrieve all the 3 lines in this case.and it should add 7+5 =12

Example2:
Code:
14:24:00,14:25:16,0,0,0
14:25:03,14:27:00:16,7,0,0
14:25:00,14:30:16,5,0,0

In this case End time is matching so it should all the 3 lines and it should add 7+5 =12

Example3:

Code:
14:23:00,14:25:16,0,0,0
14:25:03,14:27:00:16,7,0,0
14:25:00,14:30:16,5,0,0

In this case both start time and End time are matching so it should all 3 lines and it should add 7+5 =12

I am not able to perform the above action.

How can i get this in perl?

Regards
