Finding the time difference

Hi,
I have two files A.txt and B.txt. And i have the following attributes in both the files.
<date and time> <a unique id>

For eg:
<2007 May 30 20:29:36:034 GMT> <ID1> in A.txt
<2007 May 30 20:42:36:038 GMT> <ID1> in B.txt

Now, i need to find the time difference alone by retaining the unique ID and i should return the difference in a separate file C.txt.
How i can achieve this?

Please help me out.

thanks in advance.

BOMSTRIP(1)						    BSD General Commands Manual 					       BOMSTRIP(1)

NAME
bomstrip, bomstrip-files -- strip the BOM sequence from UTF-8 files SYNOPSIS
bomstrip bomstrip-files file ... DESCRIPTION
The bomstrip utility reads UTF-8 data from its standard input and copies it to its standard output, stripping the BOM (byte-order mark) from the beginning of the text if it is present. There are no command-line options and no parameters. The bomstrip-files utility removes the UTF-8 BOM from the specified files, saving each file's original contents with a .bom extension. It uses the bomstrip utility, trying to execute it as ``bomstrip''; if the bomstrip utility is installed under another name, or if a more com- plex command is desired, it may be supplied in the BOMSTRIP environment variable. EXAMPLES
Strip the BOM, if present, from a text file: bomstrip < bom.txt > nobom.txt Strip the BOM, if present, from all text files, backing them up with a .bom extension: bomstrip-files *.txt Use the OCAML implementation of bomstrip: env BOMSTRIP='ocaml bomstrip.ocaml' bomstrip-files *.txt SEE ALSO
The bomstrip home page: http://www.xs4all.nl/~mechiel/projects/bomstrip/ HISTORY
The bomstrip utility (in many languages) was written by Mechiel Lukkien, with implementations in various languages sent to him by others, including Andreas Gohr, Andrew Gerrand, Berteun Damman, Matthijs Bomhoff, Peter Pentchev, and Ruben Smelik. The bomstrip-files utility and this manual page were written by Peter Pentchev in the hope that they reflect the behavior of all the bomstrip implementations in all lan- guages. AUTHORS
