Since the equivalent European signal I'm familiar with only covers a single timezone, with unified DST rules, I'm curious:
Do these usually have an adjustment button for a time zone offset? And how do they handle DST – do they have an "I'm in Arizona (but not in the Navajo Nation), leave me on standard time" switch?
