Switch to British Summer Time causes appointment chaos for some Windows-based iPhone users

invisibleSHIELD case for iPad“iPhone users are turning to Google for help as an incompatibility with Outlook shifts appointments by an hour instead of switching on daylight saving,” Bill Ray reports for The Register.

“iTunes version 9.1 currently can’t cope with daylight saving time, shifting appointments by an hour or even a day as it struggles to cooperate with Microsoft Outlook,” Ray reports. “Given the breakdown in communication users are downgrading to the more-Outlook-friendly version 9.0, or bringing in Google as an intermediary.”

“The problem lies in the synchronisation between Microsoft Outlook and the iPhone, and the switch to daylight savings (British Summer Time),” Ray reports. “The only alternative appears to be downgrading to iTunes 9.0, which doesn’t have the problem… Apple will no doubt fix the problem in the next iTunes release, but when that will be is anyone’s guess.”

MacDailyNews Take: We’re almost positive that, before writing any article about Apple, Register hacks’ fingers are inflicted with paper cuts and then dipped in lemon juice in order to get them into a certain frame of mind. Why they hate the most innovative, paradigm-shifting tech company the world has ever seen is beyond us, but it shows through quite clearly and routinely in their hackneyed prose.

Here’s a thought: If Microsoft hadn’t knifed Outlook on the Mac (only to promise to finally bring it back well over a decade later in their next Office for Mac release) in order to give themselves and their PC box-assembling “partners” an artificial advantage in the business market – in other words, abuse their monopoly position yet again – then there wouldn’t be these type of issues today. Our iPhones work perfectly with Daylight Savings Time. Of course, we’re not trying to coax Windows and some Windows-only piece of bloatware to work, we’re using superior Apple Macs.

It’s really too bad that Apple has to invest time and resources trying to support Microsoft’s shiteous OS. The world would be at least a decade more advanced today, had the Windows mistake never been committed; a mistake that The Register inexplicably seems to want to perpetuate.

Oh, BTW: Clockwork: Microsoft can’t even get Daylight Savings Time right – March 08, 2007

  1. There’s a similar bug in Entourage and its sync with Exchange – you’re never sure whether appointments that someone has invited you to are timed as GMT or Daylight Saving time. It’s rubbish.

  2. I’m as Fanboy as the rest, but if Apple screwed up, they screwed up. Relax MDN, here’s a chance for you to accept Apple’s mistake and give yourselves a little unbiased credibility.
    Shiteous or not, Apple chose to play in the Windows playground, and gain market share by doing so. It’s up to them to fight through the crap and make a fully functioning product. If they messed up, they messed up and should be called out on it.
    Let’s hope it’s a quick fix!

  3. No, Apple is fine. It’s good old MS and the way they deal with TimeZones by ignoring problems that have plagued Outlook and Entourage for the last few years with all the new timezone adjustments.

    One of my customers is a big worldwide company with exchange and Outlook. I believe it was 1 or 2 years ago that the US moved the dates for Daylight savings time. MS did not update Exchange of Outlook in time. I had many users asking why all their meeting were off by one hour. It eventually fixed itself when the old time change date came around. Then they had the rest of summer to hammer MS to get the patch out before the fall time change.

    Another great MS strategy to ignore their existing customers and try to force them to upgrade to get support. Didn’t work.

  4. Apple’s not 100% on their own products either. I have a couple of iCal events for payments, with custom repeat settings: last weekday of every month.

    It shows up fine in iCal, but when it syncs to my iPhone 3GS the setting there reads as “repeat every (null) Monday”, and shows up on every Monday instead of what desktop iCal is set to.

  5. My guess is Microsoft hard-coded the Daylight Savings/Summer Time assumptions into their code, in numerous separate locations, and did so in a different way each time for Windows, Outlook, Entourage, etc. That’s the only explanation I can think of for why they can’t seem to get this problem to go away.

  6. I blame the arsehole who came up with the dumbass concept of Daylight Savings Time a century ago.

    After leaving Arizona which doesn’t do Daylight Savings for beachier climes I am quite irritated that it’s still light at 8pm when I’m trying to put my kid to sleep.

  7. Wait– if iPhone is failing to sync correctly to outlook and outlook is not on the mac os, how is Microsoft not shipping a Mac version the cause of this?

    If I read the vague and sloppy original article the problem is direct outlook to iPhone syncing (not Exchange, in which both phone and outlook are peer clients). In which case no outlook for mac is an irrelevance.

    If it is Exchange scenarios in question it has nothing to do with outlook.

    Either way, yet again these journalists are under-informed generalists just sort of blathering and opining on crap they don’t understand

  8. It looks like this is an issue with the last Apple’s iTunes (9.x) update and referenced in Apple’s support forum @ http://discussions.apple.com/thread.jspa?threadID=2383584&start=0&tstart=0.

    Also it looks like Apple (selectively?) released a fix for iTunes but not clear that they have been able to isolate the problem. There are reports of Apple Tech Support on the forum above of handing out two DLLs that solves the problem for now – no details on these updates.

    Until then, there is info on how to fix this yourself. http://www.examiner.com/x-19069-Indianapolis-Information-Technology-Examiner~y2010m4d14-iTunes-91075-Sync-Issue-Fix
