[LUAU] Favorite NTP server?

[Brian Chee]

Why not run your own NTP server? The stratum1 Raspberry Pi would cost under
$100 in hardware and that includes a pretty long external GPS patch antenna
that you can stick to the inside of a window.

Though the GPS unit from Adafruit has an external antenna connector and the
patch antenna is bitchin. I'm considering combining projects to do a gps
synched clock (7 segment displays) that also serves NTP.
