Ok, here is a bash example. You might have to adjust the highlighted sub-string index and length according to your finger output.
Code:
#!/bin/bash

rm -f tmp

finger | while read line
do
        if [ $( echo $line | grep -c "^Login" ) -eq 0 ]
        then
                echo "$( date -d"${line:39:12}" +"%s" ) $line" >> tmp
        fi
done

sort -n tmp | cut -c 12-
