Assuming that WWVB will persist (a medium-sized assumption) ...

The La Crosse 404-1235UA-SS UltrAtomic (not affiliated, just a fan) tracks
DST - and even leap seconds. They have much better reach than previous
similar clocks. Mine work during daytime deep inside buildings in Alaska,
far outside the traditional WWVB reach. They're also also simple and
legible, which could make them a good NOC choice. Local timezone is
adjustable, so you could easily run one on local time and one on UTC. They
also change their hand positions to indicate low-battery status. Not cheap,
but not too bad - price hovers around US$48-$52. Big fan.
