Wait, you're using "Countries change their DST and timezone policies from time to time" as an argument for storing UTC in the database? As far as I'm concerned

Wait, you're using "Countries change their DST and timezone policies from time to time" as an argument for storing UTC in the database?
As far as I'm concerned, this is the only valid argument against UTC. If a user adds an event for e.g. 2pm March 25th 2022 local time, you convert it to UTC, and then later the conversion rules for that day change, you now have a date that's been improperly converted to UTC.
I don't think it's a strong enough reason not to use UTC in the db, given the multitude of issues surrounding other choices, but I do think that it's important to be clear about the pros and cons.
