Thanks Frans for the quick response.

I think I dont have GNU date. I am working on KSH on an IBM AIX OS. Below is the error that I got.

Code:
date: Not a recognized flag: d
Usage: date [-u] [+"Field Descriptors"]
date: Not a recognized flag: d
Usage: date [-u] [+"Field Descriptors"]

Let me know if I am missing something.

Thanks,
Bharath

Ok finally found a way!! Wrote a simple awk function to do that (only time difference within a day) Atleast thats what I needed:

Function:
Code:
TimeDiff ()
{
	echo `echo "$1" | awk 'BEGIN {
   	split("3600 60 1", sec_calc)
   	FS=":|[ ][ ]*"
	}	
	{
	  time1 = 0
	  for (i=1; i < 4; i++)
	    time1 += $i * sec_calc[i]
	  
	  time2 = 0
	    for (i=4; i < 7; i++)
	    time2 += $i * sec_calc[i-3]
	
	  time_diff = time2 - time1
	  hour_diff = time_diff / 3600 
	  calc_diff = time_diff % 3600 
	  min_diff = calc_diff / 60
	  sec_diff = calc_diff % 60
	  
	  printf("%.2d:%.2d:%.2d\n",int(hour_diff),int(min_diff),sec_diff) 
	  
	}'`
}

And called the function in my script as:

Code:
UnldDT=`TimeDiff "$UnldSt $UnldEd"`
LoadDT=`TimeDiff "$LoadSt $LoadEd"`

Thanks all for your time.
