I'd like to use the opportunity to reiterate my point about abolishing #DST, in a slightly different form.

Ask yourselves a bunch of questions:

1. How many devices automatically adjust to DST today, using a date-based algorithm?
2. How many of them get automatic timezone data (or software) updates? Or at least get updated periodically? And how many are going to require an intervention to get the algorithm updated?
3. How many of them actually permit algorithm updates? How many of them get software updates? And how many use software that was long abandoned, and perhaps the sources were lost in the mists of time? In other words, how many "can't do", and we're stuck with doing manual adjustments every half a year to keep the local time correct?
4. How many of these synchronize their UTC time, therefore overwriting our local adjustments? How many of them will permit disabling this synchronization, and how many will require us to physically block it instead? And how many will end up quickly collecting clock drift once the synchronization is off?
5. In the end, how many critical devices we're going to miss entirely, just because they "always worked" and nobody remembers about them anymore?

Sometimes I feel like people are thinking of abolishing DST as if they were living a hundred years ago. Unfortunately, today we're deeply computerized, and such a change requires a lot of preparation work, and readiness to intervene when things fall apart. What it doesn't require is a bunch of noisy politicians, waking up a month before each DST switch to philosophize on their couches. And in the end, such a reform will definitely mean trashing some otherwise good hardware that doesn't get updates anymore.
