The project illustrates a use case of the websocket (ws) protocol.

• The client app sends empty request to the server.
• Upon successful handshake, the server pushes current UTC timestamp formated as the ISO string. It's done perpetually with the delay of 200 ms. between two consecutive responses.
• Client app tails and displays 20 most recent responses.
