The atomic clock radio signal is in UTC. You have to configure the clock
for a base timezone, but the signal does include embedded DST
information at the day level (the clocks are hardcoded to make the
transition at the next 2:00 local time).

AIUI it's centrally located for the whole country, so they can't send
"what timezone you are in now" data the way cell phone towers can.
