Hammer & Screwdriver Here is an approach

The following is written to run for ten seconds; adjust the 10 to the appropriate number of seconds. (I did for ten for easier testing and to see that it works.)

Code:
> cat run_time
#! /usr/bin/bash

#variables
initial_time="test_file_start"
current_time="test_file_current"
time_diff_goal=10  # the number of seconds before exit

touch $initial_time
time1=`stat -c %Y $initial_time`

while [ 1 -eq 1 ]
   do

# do some stuff here

      touch $current_time
      time2=`stat -c %Y $current_time`

      time_diff=`echo $time2 - $time1 | bc`
      if [ $time_diff -ge $time_diff_goal ]
         then
         echo $time_diff
         exit 99
      fi
done
