#! /usr/bin/ksh
echo enter first time stamp
read TIME1
echo enter second time stamp
read TIME2
H1=`echo $TIME1 | cut -d\: -f1`
M1=`echo $TIME1 | cut -d\: -f2`
H2=`echo $TIME2 | cut -d\: -f1`
M2=`echo $TIME2 | cut -d\: -f2`
S1=`echo $TIME1 | cut -d\: -f3`
S2=`echo $TIME2 | cut -d\: -f3`
#echo $H1 $M1 $S1 $H2 $M2 $S2
        if [ $H1 -eq $H2 ]
        then
                ((MA1=M1*60+S1))
                ((MA2=M2*60+S2))
                ((MA1>MA2)) && ((MA2=MA2+86400))
                ((diff=MA2-MA1))
 
                                if [ $diff -lt 10 ]
                                then
                                        diff="0"$diff

                echo $diff
        else
                ((H1>H2)) && ((H2=H2+24))
                ((diff=H2-H1))
                ((MA1=M1*60+S1))
                ((MA2=M2*60+S2))

RETURN VALUES

	Returns the formatted interval.

NOTES

       Note

	       The DateInterval::format method does not recalculate carry over points in time strings nor  in  date  segments.	This  is  expected
	      because  it is not possible to overflow values like "32 days" which could be interpreted as anything from "1 month and 4 days" to "1
	      month and 1 day".

EXAMPLES

       Example #1

	      DateInterval example

	      <?php

	      $interval = new DateInterval('P2Y4DT6H8M');
	      echo $interval->format('%d days');

	      ?>

	      The above example will output:

	      4 days

       Example #2

	      DateInterval and carry over points

	      <?php

	      $interval = new DateInterval('P32D');
	      echo $interval->format('%d days');

	      ?>

	      The above example will output:

	      32 days

       Example #3

	      DateInterval and DateTime::diff with the %a and %d modifiers

	      <?php

	      $january = new DateTime('2010-01-01');
	      $february = new DateTime('2010-02-01');
	      $interval = $february->diff($january);

	      // %a will output the total number of days.
	      echo $interval->format('%a total days')."
";

	      // While %d will only output the number of days not already covered by the
	      // month.
	      echo $interval->format('%m month, %d days');

	      ?>

	      The above example will output:

	      31 total days
	      1 month, 0 days
