Linux Script will keep checking running status of another script and also restart called script at night

I am using blow script :--


Code:
#!/bin/bash 
FIND=$(ps -elf | grep "snmp_trap.sh" | grep -v grep)         #check snmp_trap.sh is running or not
if [ $? -eq 0 ]
then
#       echo "process found"
     exit 0;
else
     echo "process not found"
exec /home/Ketan_r /snmp_trap.sh 2>&1 & disown -h     #start process in background 
proc_status=$?
     if [ $proc_status -eq 0 ]
     then
     echo "Restarted Process at `date '+%Y-%m-%d %H:%M:%S'` "
     fi
fi

crontab entry for this script
Code:
*/5 * * * * /home/Ketan_r/logs/sleep_time.sh >> /home/Ketan_r /logs/status_snmp_$(date +\%Y\%m\%d).log

now I want this script also kill and restart “snmp_trap.sh” at 11.30PM every day. I am confused, if I am use sleep to within this to kill process(sleep “time”) then it works but this script run on every 5th minute so it again execute sleep command every 5th minute and go on…..
could you please let me know what could be the possible implementation for this….

In your cron job write a first test for the time so if condition is met it kills and restart your process if not it continues with the content of your script...
