You may refer the man page of time.

real - starts counting from the moment you start the command to the command's termination, includes all scheduling delays, this would be your elapsed time.
user - how much time it has executed in used mode
sys - how much time in kernel mode
Code:
       o  The elapsed (real) time between invocation  of  utility
          and its termination.

       o  The User  CPU  time,  equivalent  to  the  sum  of  the
          tms_utime   and   tms_cutime  fields  returned  by  the
          times(2) function for the process in which  utility  is
          executed.

       o  The System CPU time,  equivalent  to  the  sum  of  the
          tms_stime and tms_cstime fields returned by the times()
          function for the process in which utility is executed.

rename your abc.ksh to abc_wrapped.ksh. and create new abc.ksh as below

Code:
#!/bin/ksh
echo `time .\abc_wrapped.ksh`

Make sure you put both the script in the same directory or change the path

hmmm.
Cant i create a new abc_wrapped.ksh and put your code in that...
Why Renaming the name of my script.

Old 06-01-2011
you can do either way. I just suggested my way. All you need a wrapper script which will have small code to print the time and will call your original script.
