Not quite what I said.
First off, TCP needs to run on machines which do not know what
the current time is.
Second, the TCP window is not in seconds, but in packets.

You should read about Bufferbloat. It turns out that excessively
large packet caches make everything worse.

Rajib, I understand that you are frustrated and looking for
solutions. The particular solutions you are proposing are not
going to work. You are reasoning by analogy, which is good for
solving many human problems, but in this case we have computer
problems, and they need to be solved by looking at the actual
protocol documents and implementation history, so that you can
understand what is actually happening.
https://tools.ietf.org/html/rfc793 TCP
https://tools.ietf.org/html/rfc7414 The 2015 TCP roadmap
- you should especially read sections 3 and 4.
Perhaps it is time to look at what your original problem is, in
the hopes of solving that?
