Also, don't forget the idea of picking up a cheap rubidium off ebay
that gives out a pretty solid 10 MHz. Use that as a crystal to drive
your microcontroller and use whatever display you like. A couple of
SLA batteries for backup and you've built your own atomic clock.

The one I've built is accurate to 1 second every century or two. Not
time-nut grade, but certainly halfway decent.
