How about
Code:
awk 'function MS(TS) {n=split (TS,TMP, "[:,]"); return ((TMP[1]*60+TMP[2])*60+TMP[3])*1000+TMP[4]} {print $0 "||" MS($8) - MS($1)}' file

shtool-mkshadow

SHTOOL-MKSHADOW.TMP(1)					      GNU Portable Shell Tool					    SHTOOL-MKSHADOW.TMP(1)

NAME

       shtool-mkshadow - GNU shtool create shadow tree using symlinks

SYNOPSIS

       shtool mkshadow [-v|--verbose] [-t|--trace] [-a|--all] src-dir dst-dir

DESCRIPTION

       This command creates a shadow tree of src-dir under dst-dir by recreating the directory hierarchy of src-dir under dst-dir and by creating
       the files of src-dir by linking them into the corresponding directories under dst-dir via symbolic links. When src-dir can be reached via
       relative paths from dst-dir, relative symbolic links are used, too. This high-level functionality is originally designed for developers to
       create copies of source trees.

OPTIONS

       The following command line options are available.

       -v, --verbose
	   Display some processing information.

       -t, --trace
	   Enable the output of the essential shell commands which are executed.

       -a, --all
	   Really shadow all files and directories in src-dir. Default is to skip CVS related files and directories, backup files, object files,
	   etc.

EXAMPLE

	#   shell script
	shtool mkshadow -v -a . /tmp/shadow

HISTORY

       The GNU shtool mkshadow command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998 for Apache. It was later
       revised and taken over into GNU shtool.

SEE ALSO

       shtool(1), ln(1).
