Using NTP is not a viable solution for a distributed mesh network. What
if the Internet is only accesible via WG, or what if the network is not
connected to the Internet at all? It's not a trivial problem, but I
think it would be benefecial to WireGuard as a project to not depend on
centralized time authority *if there is an option not to*.
