Column $4 is timestamp

Below command will print all log since 10 second ago.

awk -vDate=$(date -d"now-10 sec" +[%d/%b/%Y:%H:%M:%S) '{ if ($4 > Date) print $0}'  access_log

you can change now-10 sec to any time you want and don’t forget to change timestamp location, it may not located on $4.

Done.
