Some Apple Watch Series 4 Models Are Frequently Crashing and Rebooting Due to a Daylight Saving Time Bug (macrumors.com)

Some Apple Watch Series 4 owners in Australia experienced crashes and reboots on Saturday due to a bug that surfaced because of the daylight saving time change. From a report: According to Reddit users hit by the Apple Watch bug, the root of the problem appears to be the Infograph Modular face's Activity complication, which displays a timeline graph with hourly data for the user's Move calories, Exercise minutes, and Stand hours. When daylight saving time (DST) lops an hour off the typical 24-hour day, the Activity complication is apparently unable to compute the change and draw the timeline graph with only 23 hours, which throws the Apple Watch into an endless reboot loop until the battery runs out.

Daylight 'saving' time is a bug in any sensible timekeeping system.

This is a timely (ahem) topic in the EU, as we have recently decided to ditch the biannual idiocy for fixed timezones. The remaining problem is that member countries can decide on which timezone to use, which might not be the solar one. So proponents of DST are campaigning for year-round DST (solar + 1). To me that sounds even sillier than current DST changes -- if you're going to make it permanent, you might as well fix your working schedule instead of redefining time itself. ("I want to go to work 1 hour earlier, but I still want it to be 8 o'clock, so I'll just move the definition of 8 around until I'm satisfied.")

Meanwhile, several European countries are already on a non-solar timezone in favour of Central European Time. It's an interestingly rational alternative to solar time, but for us Finns it would be the "solar - 1" zone, in direct opposition to the DST camp. So one can hope that we'll compromise on the solar zone.
