μWWVB: A Tiny WWVB Station · cat /var/log/life
"μWWVB is a watch stand that automatically sets the time on atomic wristwatches where regular WWVB signal isn’t available. The system acquires the correct time via GPS and sets radio-controlled clocks by emulating the amplitude-modulated WWVB time signal." Awesome!

Very cute. I have fairly poor reception of the UK time signal up here in Dundee -- I'm now pondering a GPS- or NTP-locked local repeater...
Set the clock from the timestamp in a TLS handshake. Not a million miles away from my 404date script, although about a thousand times more complicated!
