And if the country you're in dares change the DST switch-over date (aka the US, during the Clinton era), you're now in an even worse situation, because you have to change it four times a year. Twice because of DST, then two more times because your clock is trying to be helpful and accommodate DST for you. That or you download the firmware, repack it with new tzdata files, and reflash the system, which as we all know, all manufacturers totally support everywhere, and for free, so doing that sounds like an easy technical exercise.
