Brazilian iPhone owners woke up 1 hour earlier today

Reddit:

Basically, a failure involving iPhone and local carrier TIM has made iPhone owners wake up 1 hour earlier today.

That’s because the smartphone adjusted automatically for daylight saving time, but that year the start of the DST was postponed to November due to the second round of presidential elections and the National High School Exam.

A small fraction of Android users was affected, but problem hit mainly iPhone users.

That’s a major oops. I wonder if Apple has a mechanism in place to deal with time changes like this.

  1. The whole world needs to just stop with the DST. It was never a really good idea to begin with.

  2. To be fair, this is a slightly different problem. Countries abruptly shift DST with little notice. Most platforms use one or two standardized libraries, which then have to be updated, and then baked into the OS.

    In this case, postponing DST due to elections and high school exam? Really? DST does need to die *and* Apple does need to get a handle on the other DST bugs, which are less trivially excusable.

  3. I thought the whole idea of cell phones was to get a timestamp from the cellular network, removing the need to set the time on the device itself.

  4. It was a joke based on “Brazilian.” 🙂

    I don’t really agree about DST needing to die. I’m far enough north that it makes the difference between kids being on streets in the dark only once per day vs. twice in the winter, and gives them a much more reasonable bed time in the summer. I think a lot of people who rant against DST have never actually looked at an almanac for their region and looked at what the sunrise/sunset times would be on June 21 and December 21 without it.

  5. DST is the difference between my kid having to cross the street once or twice in darkness, and having a reasonable bed time in the summer.

    People need to stop thinking they represent the whole world. 🙂

  6. Well, as someone who wakes up in the dark every day, my point was not to kill DST to go back to standard time, but rather permanent DST. 🙂

    The latest sunrise in this area is about 7:20am, and twilight gives another half-hour. Having it be light around 8am would be perfectly fine for me. (Interestingly, a quick scan of Seattle, Minneapolis and Boston suggests that the sunrise patterns would be similar, so it’s not necessarily north-south, but rather the time zone one’s in.)

  7. I’d certainly rather have winter time year round than summer. That would also put solar midnight/noon close to midnight/noon. It would also put civil sunrise at 3:20 AM in the summer, but what can you do?
