I may have not been clear in my last response, it was to be taken in
the context of the whole thread...

I meant to have one (or few) nodes that do provide time over UDP from
a GPS or other time-source, i.e. not connected to the Internet.
Not every node needs that.
Alternatively, as a pure software solution, every node of the network
may be required to run ntp on udp, or even other time protocol (say
RFC 867, RFC 868).
So any new node, before connecting to the WG endpoint with WG tunnel,
sets its time from it.
Nodes that do have access to the Net (exit nodes in a way), can run
ntpd internally and also don't need GPS or other time sources, if the
purpose of the network is "connect to the Net".
