Still the same error. Here is a larger portion of the code:

Code:
        ((startTime= `perl -e 'print time;'`))
	((currentTime= $startTime))
	((executeTime= $startTime))
	tempTime=`date +%H%M`


	# Check if the second command argument is exists.
	if[ "$#" <  2 ]
	then
		((endTime = $startTime + 28800))		# Add 8 hours = 28800 seconds

	# If The second command line argument isn't empty
	else
		((temp = `expr $2 - $tempTime`))
		if[ $temp < 0 ]					# If temp is negative convert it to positive
		then
			((tempHour = temp / 100))
			((tempHour = tempHour * -3600)) 	# Multiply hours by -3600 seconds per hour to make positive
			((tempMin = temp % 100))
			((tempMin = tempMin * -60))		# Multiple minutes by -60 seconds per minute to make positive
			

		else
			((tempHour = temp / 100))
			((tempHour =  tempHour * 3600)) 	# Multiply hours by 3600 seconds per hour
			((tempMin = temp % 100))
			((tempMin =  tempMin * 60))		# Multiple minutes by 60 seconds per minute
		fi

		((endTime = $endTime + $tempHour + $tempMin))
	fi

net::dns::sec::tools::timetrans

timetrans(3pm)						User Contributed Perl Documentation					    timetrans(3pm)

NAME

       Net::DNS::SEC::Tools::timetrans - Convert an integer seconds count into text units.

SYNOPSIS

	 use Net::DNS::SEC::Tools::timetrans;

	 $timestring = timetrans(86488);

	 $timestring = fuzzytimetrans(86488);

DESCRIPTION

       The timetrans() interface in Net::DNS::SEC::Tools::timetrans converts an integer seconds count into the equivalent number of days, hours,
       and minutes.  The time converted is a relative time, not an absolute time.  The returned time is given in terms of days, hours, minutes,
       and seconds, as required to express the seconds count appropriately.

       The fuzzytimetrans() interface converts an integer seconds count into the equivalent number of weeks or days or hours or minutes.  The unit
       chosen is that which is most natural for the seconds count.  One decimal place of precision is included in the result.

INTERFACES

       The interfaces to the Net::DNS::SEC::Tools::timetrans module are given below.

   timetrans()
       This routine converts an integer seconds count into the equivalent number of days, hours, and minutes.  This converted seconds count is
       returned as a text string.  The seconds count must be greater than zero or an error will be returned.

       Return Values:

	   If a valid seconds count was given, the count converted into the
	       appropriate text string will be returned.

	   An empty string is returned if no seconds count was given or if
	       the seconds count is less than one.

   fuzzytimetrans()
       This routine converts an integer seconds count into the equivalent number of weeks, days, hours, or minutes.  This converted seconds count
       is returned as a text string.  The seconds count must be greater than zero or an error will be returned.

       Return Values:

	   If a valid seconds count was given, the count converted into the
	       appropriate text string will be returned.

	   An empty string is returned if no seconds count was given or if
	       the seconds count is less than one.

EXAMPLES

       timetrans(400) returns 6 minutes, 40 seconds

       timetrans(420) returns 7 minutes

       timetrans(888) returns 14 minutes, 48 seconds

       timetrans(86400) returns 1 day

       timetrans(86488) returns 1 day, 28 seconds

       timetrans(715000) returns 8 days, 6 hours, 36 minutes, 40 second

       timetrans(720000) returns 8 days, 8 hours

       fuzzytimetrans(400) returns 6.7 minutes

       fuzzytimetrans(420) returns 7.0 minutes

       fuzzytimetrans(888) returns 14.8 minutes

       fuzzytimetrans(86400) returns 1.0 day

       fuzzytimetrans(86488) returns 1.0 day

       fuzzytimetrans(715000) returns 1.2 weeks

       fuzzytimetrans(720000) returns 1.2 weeks
