Western Australia had a three year daylight saving trial imposed on us with short notice back around 1999. A decade later it was still dangerous to try to sync a calendar through iCloud from a Mac to a PC running Outlook. And I discovered a couple of years ago that Yealink VOIP phone still get the time wrong here during summer.

#92Chilean here. Unfortunately our governments have had the bad habit of changing the date DST starts on every two-three years, and that wreaks havoc everywhere in the country. We are kind of used to having a couple of days where we assume everyone will run an hour late because of this. I just hosted some Peruvian friends this week and were amazed at the kind of power the government wields just by having the ability to…
Didn't they do the same thing in 2011? But as I recall, it was the Friday before the time change that the announcement came out. I had just recently moved to Chile, and I remember a week of looking at Google to find out what the current time was.

#93This is not novel. Look through the tzdb news and you will find many instances of similar and considerably shorter periods of notice. Just to pick a couple from last year that are unambiguous and well-documented (most you’ll have at least a bit more trouble finding first-party announcement of): 2021d: Fiji gave a month’s notice on suspending DST for the season. 2021b: Samoa gave less than a week’s notice on cancellin…
Samoa also famously skipped the 2011-12-30. Maybe "famously among software developers" is more on-point.
Was this to move to the other side of the dateline or something?

Why not just specify times are given in winter time? Invite someone over for "19:00 winter time" rather than just "19:00".
Basically, "amazed at the kind of power the government wields" only works if people follow it. You don't have to put up with that crap (until the dust has settled) when using a time zone people already know: whichever one you've been using for the past ~6 months. (That is to say, this doesn't sound like a religious country type situation where the religious leader declares a new year randomly and you could be seen as not following the holy law by using a more predictable calendar. I vaguely remember something about Israel and Windows 9x just not supporting it until the country decided these things with reasonable lead times.)

How do you fix the computers? It must take a long time to roll out changes for the computer code to deal with this

For comparison, it looks as if Punta Arenas ("the most southerly city in Chile" according to Wikipedia) is about 53 degrees south. 53 degrees north puts you around Nottingham, England (or a little north of Berlin).
Can you link the article to see why it would say that? Puerto Williams is a lot further south.
But Magallanes doesn't really matter, they don't have DST.

#97Some call it "chaos", others might call it "badly written software".
This is why I dislike custom "we'll-do-it-ourselves" solutions. Updating your operating system's tz-database is easy; it's normally a single package with no dependencies that you can install without patching the rest of your outdated operating system full of security holes if you're in an "enterprise" environment where normal updates are seemingly impossible. If you need to rebuild your application or even your Docke…
Your post is completely missing the point. Here are some examples of what I have seen go wrong:
* Microsoft didn't release an update, all Windows machines had incorrect time.
* Google Calender never got the update, it was wrong for a week. Shifting everything by one hour in your head isn't too bad but for some reason meetings scheduled by people in other timezones weren't off by an hour.
* Slack never got the update
* Managed databases running on cloud providers didn't get the update.
* A default Postgres installation will run with the tzdata shipped with Postgres, the next release is 1-2 months away. Some distros probably use the OS tzdata instead and you could recompile to fix this.
* Software using temporary credentials and MFA systems broke because timestamps mismatched.
Unless you run your whole company on homegrown code you would surely feel some pain if something like this happened in your country.
Re: Tell HN: Sudden Chile daylight savings time rules change causes chaos
#98This kind of thing is why it's important to store user-specified future dates as local time + IANA zone name. If a user wants a calendar event at 9am, they probably still mean 9am after accounting for time zone or DST changes. Storing dates as UTC is appropriate for dates in the past, or future dates that a user will never expect to happen at a certain wall-clock time. (An IANA zone name is something like America/New…
> If a user wants a calendar event at 9am, they probably still mean 9am after accounting for time zone or DST changes.
...9am of their timezone or 9am of other participants time zone ?
Countries also share a timezone, what happens when they stop ?
what if you store time in CEST but the date CEST changes into CET is different in different countries ?

#99Earlier quoted context omitted.
Not exactly what happened in the end. The house and senate in Georgia agreed on DST. However we can’t change to permanent DST yet. By Federal Law an act of Congress has to happen to change the law. https://www.fox5atlanta.com/weather/permanent-daylight-savin...
It's the same for California as well
WA, OR, and CA have all passed state laws to stay on DST. Waiting on federal govt to allow it.

Who else would have that power, though? Every government has the power to set the time within their own borders.
