Dear Experts,
This is what I've tried by converting into epoch time and it's giving me the desired result however it seems to me like this is not the standard way of doing this, do you mind taking a look and improve this solution pls.
Code:
dt1=`date -d 'Jan 19 21:15:00' +%s`
#echo $dt1
while read line
do
	tmstmp=$(echo $line | cut -c '1-15' )
	#echo $tmstmp
	dt2=`date -d "$tmstmp" +%s`
	#echo  $dt2
	echo "Ref time in epoch is $dt1"
	echo "Timestamp from file is $tmstmp"
	echo "Timestamp from file in epoch is $dt2"
	if [[ $dt2 -le $dt1 ]]
	then
		echo "This event occured before 21:15, inserting into new log file"
		echo $line >> filter.txt
	else
		continue 
		
	fi		
	
done < auth.log
