How to find the difference between time stamps in 2 different events?

[MWAKburns]

Hello!

I am have a bunch of logs stating when a job has started and finished. I have been asked to find a way to tell how long the job took to run. I am having some trouble finding the best way to do this. Here the raw data of the logs:

CONS02^NO> 18:01:09.489 18:01:10   EDTMFD FIN  
CONS02^NO> 18:01:09.089 18:01:10   FMMFD  FIN  
CONS02^NO> 18:01:09.089 18:01:10   EDTMFD START
CONS02^NO> 18:00:04.514 18:00:04   FTPFIL FIN  
CONS02^NO> 18:00:03.758 18:00:03   FTPST  FIN  
CONS02^NO> 18:00:03.758 18:00:03   FTPFIL START
CONS02^NO> 18:00:03.558 18:00:03   FTPST  START
CONS02^NO> 18:00:03.363 18:00:03   FMMFD  START
CONS02^NO> 17:55:03.753 17:55:03   FTPFIL FIN  
CONS02^NO> 17:55:03.186 17:55:03   FTPSTA FIN  
CONS02^NO> 17:55:03.186 17:55:03   FTPFIL START
CONS02^NO> 17:55:02.986 17:55:02   FTPSTA START

I have been stumped on how to make this work. I was thinking the goal output would be to combine the 2 matching job events (1 Job START and 1 Job FIN) and have the difference between the time stamps as a new field, but I am not sure if this is even possible.

Any ideas would be helpful!
