nodejs - storing client timestamps in a database

Relative newbie to Node.js so please excuse my ignorance.

I just set up a simple TCP server using the tutorial here

In my scenario, a user will connect to the server from a web browser and I am looking for a way to get access to the TCP Timestamps and eventually store them in a database.

It would be really helpful if I can get some pointers as to how I can proceed with this (client side and server side)

Thanks

You won't be able to access this low-level information. It is abstracted by the OS.

The only way to do what you are asking is to implement a packet capture.
