[kamal kannan <smkkannan@xxxxxxxxx>]

hi

 For IT compliance reasons, our ISP requested us to maintain NAT logs in
below format. We run squid with external IP and no firewall in-between
router and squid.
except End time of the request, i'm able to all other details in squid log.

Is there any way to get end time of a request.

*Below are Parameters need to be maintained *

  Start Date (mm:dd:yyyy) & Time(hh:mm:ss)
  End Date (mm:dd:yyyy)& Time (hh:mm:ss)
 Source IP address
     Source port
   Translated IP address
   Translated port
   Destination IP address
 Destination Port
