I used gensub inside st and ed array to get uids instead of st[13] as follows.

Code:

 
st[gensub(/.*>([^&]+).*/,"\\1","")]=$2

And I want to use the whole awk on lines which has INFO, How would I do it.

Also in last calculation it should be like this.

Code:

 
diff=(end*1000+e[7])-(start*1000+s[7])
