Extract info from log file and compute using time date stamp

Looking for a shell script or a simple perl script . I am new to scripting and not very good at it .

I have 2 directories . One of them holds a text file with list of files in it and the second one is a daily log which shows the file completion time. I need to co-relate both and make a report.

Code:
Directory 1 : /home/drew/files

Jan.txt
Feb.txt
Jul.txt

Contents from Jul.txt

Timestamp   Filename     Data
-----------------------------------------
2009-07-28   jnx123        3002
2009-07-29   abcd22        23423
2009-07-30   jnx123        6377
2009-07-30   abcd22        8657

Directory 2 :/home/drew/logs

server.log.2009-07-04
server.log.2009-11-30
server.log.2009-07-28

Contents of server.log.2009-07-28

2009-07-28 23:57:31,334 Loading file:jnx123
2009-07-28 23:59:32,334 Finished file:jnx123

So I want to go to the Directory 1 and open each record and run it against the server.log based on date and compute the time taken for file to load.Each day will have a server.log as mentioned and each file list will have several files a day
