30 8 * * * sleep .8 ; cd /home/req && sh notify.sh

The above code will execute notify.sh sometime after 8:30 and 800 ms. We can do better, but we'll never be exact. Consider rather than hard coding the sleep for 800 ms (.8 seconds) we determine the sleep time from the current time and sleep until the time will be more closely 8:30:00.800 .

It depends on your requirements. If you need to execute notify after 8:30:00.800, my solution works. If you want to get closer to the exact time, we have to be a little smarter.
