I have an alarm clock that sets itself based on some radio broadcast of the current time. You need to set which time zone you're in and there's a single switch to turn DST on or off.

These don't do too well in the Eastern US. WWVB is too far away. They introduced a phase modulation that has a lower SNR required for recovery, but as far as I can tell no chipsets exist that understand this signal, and only one clock exists that can receive it. (And it's an analog wall clock, so good luck with your alarms.) I use GPS for time transfer. Works great everywhere in the world.
