Hi, Is there anyway in PERL to result the person and the person count with respect to the time and date. Suppose from 11/12/2014 9:46 AM to 11/12/2014 10:03 AM, how many A or B or C occur in the following example:

      Time        Person
1   11/12/2014 9:46 A
2   11/12/2014 9:47 B
3   11/12/2014 9:48 A
4   11/12/2014 9:49 A
5   11/12/2014 9:50 A
6   11/12/2014 9:51 A
7   11/12/2014 9:52 B
8   11/12/2014 9:53 B
9   11/12/2014 9:54 B
10  11/12/2014 9:55 B
11  11/12/2014 9:56 B
12  11/12/2014 9:57 C
13  11/12/2014 9:58 C
14  11/12/2014 9:59 C
15  11/12/2014 10:00    A
16  11/12/2014 10:01    B
17  11/12/2014 10:02    C
18  11/12/2014 10:03    C

and the result I want should be the following:

Time                                Person  Total_count
11/12/2014  9:46:18 AM to 11/12/2014  10:03:18 AM   A   6
11/12/2014  9:46:18 AM to 11/12/2014  10:03:18 AM   B   7
11/12/2014  9:46:18 AM to 11/12/2014  10:03:18 AM   C   5
