I run my servers on UTC. No summertime, and I'm fine. Midnight log rolls are in a great time for me living my best life in gmt+10. I am fix things, in core body clock hours.
I read once that the Spanish nightlife only starts at midnight. That makes a lot more sense if they are on Germany’s time zone.
If you're in a position where you're scheduling meetings you hopefully have some idea of where the participants are located and try to select a time that works for the most amount of people have woken up or not yet fallen asleep.
This will probably become more of an issue with more people working remotely though.
The UK, Ireland, and European countries east of the CET-zone are on different time zones, of course, but CET stretches from Serbia to Spain. That’s not as far as Shanghai to Tibet, but it’s still at least a couple solar hours.
Going by population density CET is probably far more disruptive though. The vast majority of the population that lives in EST is, by longitude, between Detroit and Boston, which is a narrower band than between Madrid and Belgrade.
> Even in the best case scenario, it is impossible to retroactively scrap time zones. The past will always exist, and the people who lived there will never adopt your new standard. Nor can all of past history be renumbered. The history of timekeeping will remain exactly as complicated as it always has been, and the zoneinfo database can never be abandoned.
