TL;DR

This is an implementation of the Network Time Protocol, a simple algorithm or protocol that synchronizes the clocks or times between two computer systems (e.g. phone, computer, server, time server).

Time Server

• Supports multiple client time requests
• Simulates propagation delay in both directions with cmdline argument delay

Client

• Periodically sends time queries to the server to update its clock using Cristian's Algorithm
• Simulates clock drift and skew
