alt Hacker NewsThe calendar event scheduling problem is hard too.
If I'm in Sydney and I accept a 4pm meeting in 3 weeks time, say 4pm July 15 2025 in San Francisco, how should my calendar store that event's datetime and how does my calendar react to my phone changing locations/timezones?
And now try and work that out if the standard/summertime changeover happens between when the event is created in one timezone and the actual time the event (is supposed to) occur. Possibly two daylight savings time changes if Sydney goes from winter to summer time and San Francisco goes from summer to winter time - and those changeovers don't happen at the same time, perhaps not even the same week.
That's easy though. An event of such type is about an absolute point in time, so your calendar stores it like that and then displays it in your current timezone (or whatever one you specify).
When you change locations and you have your calendar configured to show events in "the" timezone of your location, it does so. And should there be no clear timezone, it should ask you.
Very simple problem and simple solutions. There are much harder problems imho.
As you can see, the summertime change does it even matter here.
