Looking at this from a &#x27;Unix in Europe&#x27; perspective, the timezone data has rules. So as long as the rules don&#x27;t change you don&#x27;t need updates. And due to the need to coordinate with many countries, timezone rules in the EU essentially don&#x27;t change.<p>It seems that in some countries, time zones just change randomly. Maybe people should just stop doing that. Countries only move a couple of centuries a year. And there is no reason to mess with DST other than to get rid of it all together.
