The Linux kernel does not track this connection lifetime, so you would
have to listen to NEW events, put the ct objects into some structure
(hashtable, tree, list, etc) and calculate the difference by yourself
once you receive DESTROY events.

It wouldn't be hard to extend the existing code to do this in kernel space.
