Subtract two rows (in Time format)

Hello all,
I have written sth like this:
Code:
#!/bin/bash
grep -e XXX -e YYYY myfile.log | grep -v ZZZ | awk '{print $1 " " $2 ";" $3 ";" $9 ";" $11}' > myfile.csv
sed -i '1iDate;Time;From;To' myfile.csv

=> it is clear that it converts log to csv and add a header.
Now I want to subtract row B3-B2,B5-B4,... which I mean I want to subtract the times. right now this is my problem Smilie
i hope someone can help me in a easy way! this is my first script.

Thanks

NAME
Template::Tools::tpage - Process templates from command line USAGE
tpage [ --define var=value ] file(s) DESCRIPTION
The tpage script is a simple wrapper around the Template Toolkit processor. Files specified by name on the command line are processed in turn by the template processor and the resulting output is sent to STDOUT and can be redirected accordingly. e.g. tpage myfile > myfile.out tpage header myfile footer > myfile.html If no file names are specified on the command line then tpage will read STDIN for input. The "--define" option can be used to set the values of template variables. e.g. tpage --define author="Andy Wardley" skeleton.pm > MyModule.pm See Template for general information about the Perl Template Toolkit and the template language and features.
