iPhone users not waking up on time due to DST bug

By on November 1, 2010, 2:26 PM
iPhone users aren't waking up on time due to a Daylight Saving Time (DST) bug. Even though the iOS clock changes correctly, the alarm does not.

Last month, users down under were woken up an hour early due to an iOS bug that caused recurring alarms to go off at the wrong time after the DST switch. It started in New Zealand and eventually hit some territories in Australia following their DST change a week later. It looks like Americans and Europeans are facing similar issues today, according to hundreds of messages on Twitter. Europeans have it the worst though: while the other regions are being woken up an hour early, those in Europe are being woken up an hour late. As a result, many are not making it to work or school on time.

It is rather shocking that Apple hasn't addressed this issue in a timely fashion (pun intended). After it happened the first time, the company promised to fix the problem, and we expect it will do so in the upcoming iOS 4.2 update (along with other bug fixes) but there's no telling when that will be. Many think the problem is that Apple's time zone programming in iOS relies on obsolete protocols for DST.

i guess they don't have money for a real alarm clock after paying too much for that paper weight

Cryptopsy said:

That is why I got late this morning at work xD

Apple's bugs fixing alarm clock must be late

My thoughts exactly. .

My old clunky $50 Razr hasn't had any problems with DST .

DST is a failed concept that will repeatedly leads to problems for everyone with no benefits to society. It may in fact be detrimental http://www.physorg.com/news187946326.html

Apples not the first to fall victim to DST software, and I'm sure it wont be the last.

This was a known issue, as the author and others have noted.

European iPhone users really have no excuse for being ignorant to this problem.

Could you clarify your last statement for me? How are they ignorant? Did Apple notify iphone users somehow that there was a bug? If so, then I completely agree with you; if not, then how can you blame the consumer for not knowing?

I'm glad Arizona doesn't do that DST crap.

Isn't DST time in America next week, the 8th?... Seems like a lot of people are using this bug as an excuse to be late on a Monday after a holiday...

We already found out about this down here in OZ. Turns out Apple didn't believe us when we said that their clocks weren't working.

posermobile89 said:

now is it the users fault that their alarms goes off late, like maybe the held the iPhone wrong while setting the alarm or something. Should they buy something to fix it

As someone whose been using a cellphone as an alarm in the morning for years, I'd be pretty angry if this happened to me.

@Flipcharm Like Carvin said, unless Apple made this known to ALL there customers it's bit naive to blame the consumer.

Razerblade said:

I do not understand why the phone would put the alarm forward an hour. The alarm only needs to stay the same, its the clock that goes back! This has been a basic feature on phones for years!

Timonius Timonius said:

that is funny...maybe apple will force the world to ditch DST finally.

ruzveh said:

lol.. iphone users dont use clock alarm?

Recipe7 Recipe7 said:

I had to laugh when I read the title of this article. One of the most simplest and crucial aspects of a phone is it's capability to remind you of things. We all know the iPhone is not just a phone... and apparently it's hype leads us to believe that it is an alarm clock too, but unfortunately it wont say sorry once you are late to work. Haha.

AzHP said:

The same thing happened to me with my clock that "automatically" changes based on DST...but it's been wrong ever since Bush's extending of DST. I hate DST with a passion, and Bush just made it more annoying.

I don't know how Apple can't fix this with an update, but it's pretty ridiculous.

People it's still better to use your old alarm clock to wake up :P

Lots of my colleagues turned up to work at 10am lol. We should be thanking Mr Jobs for an extra hour of sleep on Monday morning!

On a side note why the hell does DST/BST exist anyway?

i'm pretty sure some retarded looser will sue Apple for getting late to work due to this bug. in USA everything is possible now, gay marriage, Jedi religion, etc.

My graphics designer friend has been raging about this bug. lol

haha! this got me too, was late to work this morning (because I was on holiday yesterday) and I was late because my girlfriend ended up having to kick me out of bed!

Silly iPhone, you can guide me through france but you can't even wake me up in the morning!

It's not Apple's fault. They'll find way to blame the time change on someone else. Like governments for not adopting Apple's standards for time synchronization.

zogo said:


We are depending on cell phones too much.

I'm using my old alarm clock from now on!

frodough said:

iphone, high tech, max style, full of trivia bugs but hey no one complaints b/c users are busy paying for apps to ease their pain - ouch

63Jax said:

you know what, in Europe people doesn't like iPhone that much, Apple is made mostly for USA, for people like Kim Kardashian, metrosexuals, ''constipated'' chicks and mostly for those who don't know much about technology and the looks is more important than the smarts.

hitech0101 said:
