--------

You can do better than RPi, since a NTP server basically
only needs to understand two packets:  IP/UDP at port 123
and ARP packets.

There are WiFi enabled microcontrollers that could be taught how
to do that, but you'd have to write up your NTP daemon from scratch
which is not hard when you do not have to do the "sync clock from
remote servers" part.
