A month back, we had written about the Daylight Saving Time bug in the latest version of iOS that affected iPhone users in New Zealand by triggering the alarm an hour ahead of schedule.
As noted back then, the problem arose after the country switched to Daylight Saving Time in late September. This issue had also spread to Australia the following week as iPhone users in the island nation switeched to Daylight Saving Time.
It now appears that iPhone users in Europe and Middle East too have been experiencing similar issues after these countries switched over to Standard Time yesterday. However, unlike the Southern Hemisphere where the bug caused the alarm to go off an hour earlier, iPhones in the Northern Hemisphere are seemingly triggered an hour late. This has quite evidently resulted in a lot of iPhone users waking up late for work or school.
You can checkout the video demo of the daylight saving time bug:
It is worth noting that Apple has acknowledged the issue and has promised to fix the bug in the upcoming iOS 4.2 update.
But since users in the United States are scheduled to switch back to Standard Time on November 7, it will be interesting to see if Apple releases iOS 4.2 this week to avoid many more iPhone users getting affected by this bug.
Nevertheless, if you are one of those users who have been affected by this issue already, do note that a temporary fix to the problem can be achieved by turning off the recurring alarm on your iPhone and instead relying on the single use alarm (not ideal). Alternately, you may also set your alarm to go off an hour earlier (in the northern hemisphere) or later (in the southern hemisphere) as need be.
