i have written a script to take the time difference of two time stamp please modify it as you need
Code:
awk -v start_time=$1 -v end_time=$2 'BEGIN{
if ( start_time !~ /^[0-9]/ || end_time !~ /^[0-9]/ )
usage(start_time,end_time)
split(start_time,T2,":")
split(end_time,T1,":")
start_seconds=T1[1]*60*60+T1[2]*60+T1[3]
end_seconds=T2[1]*60*60+T2[2]*60+T2[3]
if ( start_seconds > 86401 || end_seconds > 86401)
usage("out_off_range","")
elapsed_seconds=start_seconds-end_seconds
if( elapsed_seconds < 0 )
{elapsed_seconds=elapsed_seconds*-1
calculate(end_time,start_time,elapsed_seconds)}
else
calculate(start_time,end_time,elapsed_seconds)}
function calculate(start_time,end_time,elapsed_seconds){
HH=elapsed_seconds / 3600
MM=(elapsed_seconds % 3600) / 60
SS=elapsed_seconds % 60
printf  "TIME DIFFERENCE BETWEEN "start_time"(START TIME)-"end_time"(END TIME)--> +%02d:%02d:%02d\n",HH,MM,SS }
function usage(start_time,end_time){
if( start_time=="out_off_range" )
printf "TIME OUT OFF RANGE\n"
else
printf "INVALID TIME FORMAT "start_time" "end_time"\n"
printf "USAGE : time_diff.sh <HH:MM[:SS]> <HH:MM[:SS]>\n"
exit}'

dancer::timer

Dancer::Timer(3pm)					User Contributed Perl Documentation					Dancer::Timer(3pm)

NAME

       Dancer::Timer - a timer for Dancer

SYNOPSIS

	   use Dancer::Timer;

	   my $timer = Dancer::Timer->new();
	   my $time  = $timer->tick;
	   print "[$time]: Doing something
";

	   # (time passes)
	   $time = $timer->tick;
	   print "[$time]: Doing something else
";

	   # (time passes)
	   $time = $timer->to_string;
	   print "[$time]: Doing another thing
";

DESCRIPTION

       Dancer::Timer provides Dancer with a timing object to clock operations. For example, you might want a logging that shows you when each
       operation happened (at what time) to determine how long each operation was in order to know where to focus on for possible bugs or perhaps
       unnecessary slowness.

       Dancer uses Dancer::Timer in facilities that want to provide this for you. Any plugin author is more than welcome to use it as well.

ATTRIBUTES

   start_time
       Retains the starting time of the timer. The default value is when the object is created. It fetches that using "gettimeofday" from
       Time::HiRes.

METHODS

   init
       This method is called when "->new()" is called. It initializes the "start_time" attribute.

   tick
       Creates a tick in the timer and returns the interval between the "start_time" and now.

   to_string
       Same as "tick", just more expressive.
