Try :

Code:
$ awk '{split($2,S,":");split($4,E,":");print $0, ((S[1]*3600+S[2]*60+S[3])-(E[1]*3600+E[2]*60+E[3]))/3600}' file

Oh Sorry I didn't see use this, codetag please...

Code:
while read line; do
    IFS=' '; read -r  s1 s2 s3 s4 _ _ <<< $line
    echo  $line $((  ( $(date --date="$s1 $s2" +%s) - $(date --date="$s3 $s4" +%s) )/3600 ))
done <"file"

Just hours in bash
Code:
$ bash diff.sh

2013-11-23 15:51:23 2013-11-23 12:59:28 SUR119 SAU 2

OR

Code:
$ awk  '{s=$1 " "$2;t=$3" "$4;gsub(/\-|:/," ",s);gsub(/\-|:/," ",t); print $0, (mktime(s)-mktime(t))/3600}' file

Code:

2013-11-23 15:51:23 2013-11-23 12:59:28 SUR119 SAU 2.86528

to round use int function like this
Code:
$ awk  '{s=$1 " "$2;t=$3" "$4;gsub(/\-|:/," ",s);gsub(/\-|:/," ",t); print $0, int((mktime(s)-mktime(t))/3600)}' file

which OS ? if Solaris/Sun OS then use nawk

I am very sad that though you are member since 2007, you have been very consistent in not using codetag. and secondly you have not copied the code properly.
